Release 2.13.2

Bug fixes and minor changes

Fix a bug where adding documents with numeric lists to an unstructured index results in a 500 error. Now, Marqo successfully processes the document batch, and returns a 400 error only for individual documents that contain numeric lists(1034).
Fix validation of custom vector fields. Custom vector fields were silently ignored when not specified as tensor fields for an unstructured index. This will now trigger a 400 error. This helps guide users to properly define the field as a tensor field(1034).
Improve the bootstrapping process to prevent Marqo from crashing during startup when the vector store takes longer to converge, especially with multiple indexes. This ensures a smoother startup process even if the vector store takes time to fully initialize(1036).

Release 2.13.1

Bug fixes and minor changes

Fix a bug where Marqo returns a 500 error if an inaccessible private image is encountered in the query or embed endpoint. Marqo now correctly returns a 400 error with a helpful error message (1027).
Fix a bug preventing Marqo from warming up Languagebind models. Marqo now successfully warms up Languagebind models as expected (1031).
Fix a bug where Languagebind models always generate normalized embeddings for non-text content. These models now correctly produce unnormalized embeddings for video, audio, and image content (1032).

Release 2.13.0

New features

Searchable attributes for unstructured indexes (#968). This new feature allows you to specify which lexical or tensor fields to include in your search queries, providing greater control over the search process. By customizing your search parameters, you can enhance the precision of your results across all search types: tensor, lexical, and hybrid. This feature is available for unstructured indexes created with Marqo 2.13 or later. For detailed guidance, please refer to the API reference and comparison of unstructured and structured indexes
Support for stella_en_400M_v5 embedding models (#1021). This feature adds compatibility for the Stella 400M text embedding models, enhancing the versatility of Marqo in handling diverse model types. Users can now use the hf_stella model type in their custom models. Please refer to stella model guide for details.
Allow specifying pooling method for Hugging Face models (#954). Marqo can now infer the pooling method and accept user provided pooling method in model properties. For detailed examples, please refer to this document about bringing your own Hugging Face model.

Bug fixes and minor changes

Normalize custom vectors during indexing when normalizeEmbeddings is set to True for indexes created with Marqo 2.13 or later (#970). This fix ensures that custom vector fields align with other tensor fields in terms of normalization, resulting in more accurate search results and improved overall performance.
Enhanced query parser for double quotes (#979). This feature introduces improved parsing logic for handling double quotes in search queries, allowing for greater flexibility and resilience against syntax errors. Badly formatted and escaped quotes no longer lead to 500 status errors. Please refer to the lexical search guide for more details and examples.
Bug fix for score modifiers handling (#1008). This update resolves an issue related to the handling of score modifiers in queries, specifically those involving the period . character. Users will now experience smoother query operations without encountering internal errors, ensuring that score modifiers are correctly applied.
Bug fixes for media download and query handling (#1022). Users can now successfully download private media files by using the new mediaDownloadHeaders parameter, which will replace the deprecated imageDownloadHeaders. Additionally, the fix resolves issues preventing the inclusion of more than two modalities in weighted queries, along with support for indexing .png images in Languagebind models.

Release 2.8.2

Bug fixes and minor changes

Fix an issue in Marqo where loading some models (e.g., open_clip/xlm-roberta-base-ViT-B-32/laion5b_s13b_b90k) is unsuccessful. This was resolved by upgrading the transformers and optimum packages. (#868)

Release 2.8.1

Bug fixes and minor changes

Fix a bug in Marqo where a 500 error is returned for the entire batch of documents when encountering an invalid document ID during image downloading. Marqo now correctly returns an error and rejects the invalid document, allowing successful indexing of other valid documents with a 200 response. (#860)

Release 2.8.0

New features

Improve add_documents memory efficiency and throughput for CLIP and Open_CLIP models when indexing documents with images when no patch method is used (#849). The image downloading and preprocessing logic has been improved. Marqo now converts the images to tensors directly after downloading. In our tests, the memory usage has been reduced by 37.5% and the throughput has been increased by 7.5% (subject to your settings). Marqo is also more stable when indexing documents in a multi-threading scenario.
Add support for pre-warming patch models (#847). See usage (here)

Bug fixes and minor changes

Support lexical search with only a filter (https://github.com/marqo-ai/marqo/pull/840). Marqo now supports a match-all query ("*") with a filter in lexical search. This allows you to search your documents solely based on the filter content without considering the relevance. This is a community-requested feature (https://github.com/marqo-ai/marqo/issues/770, https://github.com/marqo-ai/marqo/issues/771) and we love to hear from our users.

Bug fixes and minor changes

Improve the thread safety of index creation and deletion operations (https://github.com/marqo-ai/marqo/pull/838). Marqo now returns an operation_conflict_error(409) if users try to delete or create an index when there is another index creation or deletion in progress.
Fix a bug that an empty string lexical search query ("") returns a 500 error (https://github.com/marqo-ai/marqo/pull/840). Marqo now returns an empty search result for such a query.
Address verbose logging at the WARNING level when attributes_to_retrieve excludes fields required to build highlights. (https://github.com/marqo-ai/marqo/pull/837)

Release 2.0.0

New features

Significant queries-per-second (QPS) and latency improvements in addition to reduced memory and storage requirements. Get a higher QPS and a lower latency for the same infrastructure cost, or get the same performance for much cheaper! In our large-scale experiments, we have achieved 2x QPS improvement, 2x speed-up in P50 search latency and 2.3x speed-up in P99 search latency, compared to previous Marqo versions.
Significantly improved recall. You can now get up to 99% recall (depending on your dataset and configuration) without sacrificing performance.
Support for bfloat16 numeric type. Index 2x more vectors with the same amount of memory for a minimal reduction in recall and performance.
Structured index. You can now create structured indexes, which provide better data validation, higher performance, better recall and better memory efficiency.
New API search parameter efSearch. Search API now accepts an optional efSearch parameter which allows you to fine-tune the underlying HNSW search. Increase efSearch to improve recall at a minor cost of QPS and latency. See here for usage.
Exact nearest neighbour search. Set "approximate": false in the Search API body to perform an exact nearest neighbour search. This is useful for calculating recall and finding the best efSearch for your dataset. See here for usage.
New approximate nearest neighbour space types. Marqo now supports euclidean, angular, dotproduct, prenormalized-angular, and hamming distance metrics. L1, L2 and Linf distance metrics are no longer supported. The distance metric determines how Marqo calculates the closeness between indexed documents and search queries.
Easier local runs. Simply run docker run -p 8882:8882 marqoai/marqo:2.0.0 to start Marqo locally on both ARM64 (M-series Macs) and AMD64 machines.

Breaking changes

Create index API no longer accept the index_defaults parameter. Attributes previously defined in this object, like textPreprocessing, are now moved out to the top level settings object. See here for details.
Create index API's filterStringMaxLength parameter determines the maximum length of strings that are indexed for filtering (default value 20 characters). This limitation does not apply to structured indexes. See here for details.
Most APIs now require camel case request bodies and return camel case responses. See create index, search and add documents for a few examples.
New Marqo configuration parameters See here for usage.
Search response _highlights attribute is now a list of dictionaries. See here for new usage.
Add documents multimodal fields are defined as normal fields and not dictionaries. Furthermore, the mappings object is optional for structured indexes. See here for usage.
Add documents does not accept the refresh parameter anymore.
The following features are available in Marqo 1.5, but are not supported by Marqo 2.0 and will be added in future releases:
- Separate models for search and add documents
- Prefixes for text chunks and queries
- Configurable document count limit for add documents. There is a non-configurable limit of 128 in Marqo 2.0.
- Custom (externally generated) vectors and no_model option for index creation.
- Optional Search API q parameter when searching with context vectors.

Releases 1.5.1

Bug fixes and minor changes

Adding no_model to MARQO_MODELS_TO_PRELOAD no longer causes an error on startup. Preloading process is simply skipped for this model #657.

Release 1.5.0

New Features

Separate model for search and add documents (#633). Using the search_model and search_model_properties key in index_defaults allows you to specify a model specifically to be used for searching. This is useful for using a different model for search than what is used for add_documents. Learn how to use search_model here.
Prefixes for text chunks and queries enabled to improve retrieval for specific models (#643). These prefixes are defined at the model_properties level, but can be overriden at index creation, add documents, or search time. Learn how to use prefixes for add_documents here and search here.

Bug fixes and minor changes

Upgraded open_clip_torch, timm, and safetensors for access to new models (#646).
Documents containing multimodal objects that encounter errors in processing are rejected with a 400 error (#631).
Updated README: More detailed explanations, fixed formatting issues (#629, #642).

Release 1.4.0

Breaking Changes

Configurable document count limit for add_documents() calls (#592). This mitigates Marqo getting overloaded due to add_documents requests with a very high number of documents. If you are adding documents in batches larger than the default (64), you will now receive an error. You can ensure your add_documents request complies to this limit by setting the Python client’s client_batch_size or changing this limit via the MARQO_MAX_ADD_DOCS_COUNT variable. Read more on configuring the doc count limit here.
Default refresh value for add_documents() and delete_documents() set to false (#601). This prevents unnecessary refreshes, which can negatively impact search and add_documents performance, especially for applications that are constantly adding or deleting documents. If you search or get documents immediately after adding or deleting documents, you may still get some extra or missing documents. To see results of these operations more immediately, simply set the refresh parameter to true. Read more on this parameter here.

New Features

Custom vector field type added (#610). You can now add externally generated vectors to Marqo documents! See usage here.
no_model option added for index creation (#617). This allows for indexes that do no vectorisation, providing easy use of custom vectors with no risk of accidentally mixing them up with Marqo-generated vectors. See usage here.
The search endpoint's q parameter is now optional if context vectors are provided. (#617). This is particularly useful when using context vectors to search across your documents that have custom vector fields. See usage here.
Configurable retries added to backend requests (#623). This makes add_documents() and search() requests more resilient to transient network errors. Use with caution, as retries in Marqo will change the consistency guarantees for these endpoints. For more control over retry error handling, you can leave retry attempts at the default value (0) and implement your own backend communication error handling. See retry configuration instructions and how it impacts these endpoints' behaviour here.
More informative delete_documents() response (#619). The response object now includes a list of document ids, status codes, and results (success or reason for failure). See delete documents usage here.
Friendlier startup experience (#600). Startup output has been condensed, with unhelpful log messages removed. More detailed logs can be accessed by setting MARQO_LOG_LEVEL to debug.

Bug fixes and minor changes

Updated README: added Haystack integration, tips, and fixed links (#593, #602, #616).
Stabilized test suite by adding score modifiers search tests (#596) and migrating test images to S3 (#594).
bulk added as an illegal index name (#598). This prevents conflicts with the /bulk endpoint.

Dockerfile optimisation (#569). A pre-built Marqo base image results in reduced image layers and increased build speed, meaning neater docker pulls and an overall better development experience.

Bug fixes and minor changes

Major README overhaul (#573). The README has been revamped with up-to-date examples and easier to follow instructions.
New security policy (#574).
Improved testing pipeline (#582) & (#586). Tests now trigger on pull request updates. This results in safer and easier merges to mainline.
Updated requirements files. Now the requirements.dev.txt should be used to install requirements for development environments (#569). Version pins for protobuf & onnx have been removed while a version pin for anyio has been added (#581, & #589).

Release 1.2.0

New features

Storage status in health check endpoint (#555 & #559). The GET /indexes/{index-name}/health endpoint's backend object will now return the boolean storage_is_available, to indicate if there is remaining storage space. If space is not available, health status will now return yellow. See here for detailed usage.
Score Modifiers search optimization (#566). This optimization reduces latency for searches with the score_modifiers parameter when field names or weights are changed. See here for detailed usage.

Bug fixes and minor changes

Improved error message for full storage (#555 & #559). When storage is full, Marqo will return 400 Bad Request instead of 429 Too Many Requests.
Searching with a zero vector now returns an empty list instead of an internal error (#562).

Release 1.1.0

New features

New field numberOfVectors in the get_stats response object (https://github.com/marqo-ai/marqo/pull/553). This field counts all vectors from all documents in a given index. See here for detailed usage.
New per-index health check endpoint GET /indexes/{index_name}/health (https://github.com/marqo-ai/marqo/pull/552). This replaces the cluster-level health check endpoint, GET /health, which is deprecated and will be removed in Marqo 2.0.0. See here for detailed usage.

Bug fixes and minor changes

Improved image download validation and resource management (https://github.com/marqo-ai/marqo/pull/551). Image downloading in Marqo is more stable and resource-efficient now.
Adding documents now returns an error when tensorFields is not specified explicitly (https://github.com/marqo-ai/marqo/pull/554). This prevents users accidentally creating unwanted tensor fields.

Contributor shout-outs

Thank you for the vibrant discussion in our forum. We love hearing your questions and about your use cases.

Release 1.0.0

Breaking Changes

New parameter tensor_fields will replace non_tensor_fields in the add_documents endpoint (https://github.com/marqo-ai/marqo/pull/538). Only fields in tensor_fields will have embeddings generated, offering more granular control over which fields are vectorised. See here for the full list of add_documents parameters and their usage. The non_tensor_fields parameter is deprecated and will be removed in a future release. Calls to add_documents with neither of these parameters specified will now fail.
Multiple tensor field optimisation (#530). This optimisation results in faster and more stable searches across multiple tensor fields. Please note that indexed documents will now have a different internal document structure, so documents indexed with previous Marqo versions cannot be searched with this version, and vice versa.
The add_documents endpoint's request body is now an object, with the list of documents under the documents key (#535). The query parameters use_existing_tensors, image_download_headers, model_auth, and mappings have been moved to the body as optional keys, and support for these parameters in the query string is deprecated. This change results in shorter URLs and better readability, as values for these parameters no longer need to be URL-encoded. See here for the new add_documents API usage. Backwards compatibility is supported at the moment but will be removed in a future release.
Better validation for index creation with custom models (https://github.com/marqo-ai/marqo/pull/530). When creating an index with a model not in the registry, Marqo will check if model_properties is specified with a proper dimension, and raise an error if not. See here for a guide on using custom models. This validation is now done at index creation time, rather than at add documents or search time.
Stricter filter_string syntax for search (#530). The filter_string parameter must have special Lucene characters escaped with a backslash (\) to filter as expected. This will affect filtering on field names or content that contains special characters. See here for more information on special characters and see here for a guide on using Marqo filter strings.
Removed server-side batching (batch_size parameter) for the add_documents endpoint (#527). Instead, client-side batching is encouraged (use client_batch_size instead of server_batch_size in the python client).

New Features

Multi-field pagination (#530). The offset parameter in search can now be used to paginate through results spanning multiple searchable_attributes. This works for both TENSOR and LEXICAL search. See here for a guide on pagination.
Optimised default index configuration (https://github.com/marqo-ai/marqo/pull/540).

Bug Fixes & Minor Changes

Removed or updated all references to outdated features in the examples and the README (https://github.com/marqo-ai/marqo/pull/529).
Enhanced bulk search test stability (https://github.com/marqo-ai/marqo/pull/544).

Contributor shout-outs

Thank you to our 3.2k stargazers!
We've finally come to our first major release, Marqo 1.0.0! Thanks to all our users and contributors, new and old, for your feedback and support to help us reach this huge milestone. We're excited to continue building Marqo with you. Happy searching!

Release 0.1.0

New features

Telemetry. Marqo now includes various timing metrics for the search, bulk_search and add_documents endpoints when the query parameter telemetry=True is specified (https://github.com/marqo-ai/marqo/pull/506). The metrics will be returned in the response body and provide a breakdown of latencies for various stages of the API call.
Consolidate default device to CUDA when available (https://github.com/marqo-ai/marqo/pull/508). By default, Marqo now uses CUDA devices for search and indexing if available. See here for more information. This helps ensure you get the best indexing and search experience without having to explicitly add the device parameter to search and add_documents calls.
Model download integrity verification (https://github.com/marqo-ai/marqo/pull/502). Model files are validated and removed if corrupted during download. This helps ensure that models are not loaded if they are corrupted.

Breaking changes

Remove deprecated add_or_update_documents endpoint (https://github.com/marqo-ai/marqo/pull/517).
Disable automatic index creation. Marqo will no longer automatically create an index if it does not exist (https://github.com/marqo-ai/marqo/pull/516). Attempting to add documents to a non-existent index will now result in an error. This helps provide more certainty about the properties of the index you are adding documents to, and also helps prevent accidental indexing to the wrong index.
Remove parallel indexing (https://github.com/marqo-ai/marqo/pull/523). Marqo no longer supports server-side parallel indexing. This helps deliver a more stable and efficient indexing experience. Parallelisation can still be implemented by the user.

Bug fixes and minor changes

Improve error messages (https://github.com/marqo-ai/marqo/pull/494, https://github.com/marqo-ai/marqo/pull/499).
Improve API request validation (https://github.com/marqo-ai/marqo/pull/495).
Add new multimodal search example (https://github.com/marqo-ai/marqo/pull/503).
Remove autocast for CPU to speed up vectorisation on ARM64 machines (https://github.com/marqo-ai/marqo/pull/491).
Enhance test stability (https://github.com/marqo-ai/marqo/pull/514).
Ignore .kibana index (https://github.com/marqo-ai/marqo/pull/512).
Improve handling of whitespace when indexing documents (https://github.com/marqo-ai/marqo/pull/521).
Update CUDA version to 11.4.3 (https://github.com/marqo-ai/marqo/pull/525).

Release 0.0.20

New features

Custom model pre-loading (https://github.com/marqo-ai/marqo/pull/475). Public CLIP and OpenCLIP models specified by URL can now be loaded on Marqo startup via the MARQO_MODELS_TO_PRELOAD environment variable. These must be formatted as JSON objects with model and model_properties. See here (configuring pre-loaded models) for usage.

Bug fixes and minor changes

Fixed arm64 build issue caused by package version conflicts (https://github.com/marqo-ai/marqo/pull/478)

Release 0.0.19

New features

Model authorisation(https://github.com/marqo-ai/marqo/pull/460). Non-public OpenCLIP and CLIP models can now be loaded from Hugging Face and AWS s3 via the model_location settings object and model_auth. See here (model auth during search) and here (model auth during add_documents) for usage.
Max replicas configuration (https://github.com/marqo-ai/marqo/pull/465). Marqo admins now have more control over the max number of replicas that can be set for indexes on the Marqo instance. See here for how to configure this.

Breaking changes

Marqo now allows for a maximum of 1 replica per index by default (https://github.com/marqo-ai/marqo/pull/465).

Bug fixes and minor changes

README improvements (https://github.com/marqo-ai/marqo/pull/468)

New features

New E5 model type is available (https://github.com/marqo-ai/marqo/pull/419). E5 models are state of the art general-purpose text embedding models that obtained the best results on the MTEB benchmark when released in Dec 2022. Read more about these models here.
Automatic model ejection (https://github.com/marqo-ai/marqo/pull/372). Automatic model ejection helps prevent out-of-memory (OOM) errors on machines with a larger amount of CPU memory (16GB+) by ejecting the least recently used model.
Speech processing article and example (https://github.com/marqo-ai/marqo/pull/431). @OwenPendrighElliott demonstrates how you can build and query a Marqo index from audio clips.

Optimisations

Delete optimisation (https://github.com/marqo-ai/marqo/pull/436). The /delete endpoint can now handle a higher volume of requests.
Inference calls can now execute in batches, with batch size configurable by an environment variable (https://github.com/marqo-ai/marqo/pull/376).

Bug fixes and minor changes

Release 0.0.17

New features

New parameters that allow tweaking of Marqo indexes' underlying HNSW graph. ef_construction and m can be defined at index time (https://github.com/marqo-ai/marqo/pull/386, https://github.com/marqo-ai/marqo/pull/420, https://github.com/marqo-ai/marqo/pull/421), giving you more control over the relevancy/speed tradeoff. See usage and more details here.
Score modification fields (https://github.com/marqo-ai/marqo/pull/414). Rank documents using knn similarity in addition to document metadata ( https://github.com/marqo-ai/marqo/pull/414). This allows integer or float fields from a document to bias a document's score during the knn search and allows additional ranking signals to be used. Use cases include giving more reputable documents higher weighting and de-duplicating search results. See usage here.

Bug fixes and minor changes

Added validation for unknown parameters during bulk search (https://github.com/marqo-ai/marqo/pull/413).
Improved concurrency handling when adding documents to an index as it's being deleted (https://github.com/marqo-ai/marqo/pull/407).

Release 0.0.16

New features

Bulk search (https://github.com/marqo-ai/marqo/pull/363, https://github.com/marqo-ai/marqo/pull/373). Conduct multiple searches with just one request. This improves search throughput in Marqo by parallelising multiple search queries in a single API call. The average search time can be decreased up to 30%, depending on your devices and models. Check out the usage guide here
Configurable number of index replicas (https://github.com/marqo-ai/marqo/pull/391). You can now configure how many replicas to make for an index in Marqo using the number_of_replicas parameter. Marqo makes 1 replica by default. We recommend having at least one replica to prevent data loss. See the usage guide here
Use your own vectors during searches (https://github.com/marqo-ai/marqo/pull/381). Use your own vectors as context for your queries. Your vectors will be incorporated into the query using a weighted sum approach, allowing you to reduce the number of inference requests for duplicated content. Check out the usage guide here

Bug fixes and minor changes

Fixed a bug where some OpenCLIP models were unable to load checkpoints from the cache (https://github.com/marqo-ai/marqo/pull/387).
Fixed a bug where multimodal search vectors are not combined based on expected weights (https://github.com/marqo-ai/marqo/pull/384).
Fixed a bug where multimodal document vectors are not combined in an expected way. numpy.sum was used rather than numpy.mean. (https://github.com/marqo-ai/marqo/pull/384).
Fixed a bug where an unexpected error is thrown when using_existing_tensor = True and documents are added with duplicate IDs (https://github.com/marqo-ai/marqo/pull/390).
Fixed a bug where the index settings validation did not catch the model field if it is in the incorrect part of the settings json (https://github.com/marqo-ai/marqo/pull/365).
Added missing descriptions and requirement files on our GPT-examples (https://github.com/marqo-ai/marqo/pull/349).
Updated the instructions to start Marqo-os (https://github.com/marqo-ai/marqo/pull/371).
Improved the Marqo start-up time by incorporating the downloading of the punkt tokenizer into the dockerfile (https://github.com/marqo-ai/marqo/pull/346).

Release 0.0.14

New features

use_existing_tensors flag, for add_documents (https://github.com/marqo-ai/marqo/pull/335). Use existing Marqo tensors to autofill unchanged tensor fields, for existing documents. This lets you quickly add new metadata while minimising inference operations. See usage here.
image_download_headers parameter for search and add_documents (https://github.com/marqo-ai/marqo/pull/336). Index and search non-publicly available images. Add image download auth information to add_documents and search requests. See usage here.

Optimisations

The index cache is now updated on intervals of 2 seconds (https://github.com/marqo-ai/marqo/pull/333), rather than on every search. This reduces the pressure on Marqo-OS, allowing for greater search and indexing throughput.

Bug fixes

Helpful validation errors for invalid index settings (https://github.com/marqo-ai/marqo/pull/330). Helpful error messages allow for a smoother getting-started experience.
Automatic precision conversion to fp32 when using fp16 models on CPU (https://github.com/marqo-ai/marqo/pull/331).
Broadening of the types of image download errors gracefully handled. (https://github.com/marqo-ai/marqo/pull/321)

Release 0.0.8

New features

Get indexes endpoint: GET /indexes (#181). Use this endpoint to inspect existing Marqo indexes. Read about usage here.
Non-tensor fields(#161). During the indexing phase, mark fields as non-tensor to prevent tensors being created for them. This helps speed up indexing and reduce storage for fields where keyword search is good enough. For example: email, name and categorical fields. These fields can still be used for filtering. Read about usage here.
Configurable preloaded models(#155). Specify which machine learning model to load as Marqo starts. This prevents a delay during initial search and index commands after Marqo starts. Read about usage here.

The Python client's add_documents() and update_documents() batch_size parameter has been replaced by server_batch_size and client_batch_size parameters (py-marqo#27), (py-marqo#28)

Non-breaking data model changes

Each text field just creates a top level Marqo-os text field, without any keywords (#135)
Very large fields get their tensor_facet keywords ignored, rather than Marqo-OS preventing the doc being indexed (#135)
Tensor facets can no longer have _id as a filtering field (#135)

Bug fixes and minor changes

FastAPI runs with better concurrency (#128)
Get documents by IDs and lexical search and no longer returns vectors if expose_facets isn't specified
Fixed batching bug in Python client (py-marqo#28)

Caveats

If a large request to add_documents or update_documents results in a document adding fields such that the index field limit is exceeded, the entire operation will fail (without resilience). Mitigate this sending add_documents and update_documents requests with smaller batches of documents.
For optimal indexing of large volumes of images, we recommend that the images are hosted on the same region and cloud provider as Marqo.
