docs: Add documentation of `ElasticsearchStore.BM25RetrievalStrategy` #20098

g-votte · 2024-04-06T03:07:09Z

This pull request follows up on #19314 and langchain-ai/langchain-elastic#6, adding documentation for the ElasticsearchStore.BM25RetrievalStrategy.

Like other retrieval strategies, we are now introducing BM25RetrievalStrategy.

Background

The BM25RetrievalStrategy has been introduced to langchain-elastic via the pull request Enable ElasticsearchStore to retrieve with the pure BM25 algorithm without vector search langchain-elastic#6.
This PR was initially created in the main langchain repository but was moved to langchain-elastic during the review process due to the migration of the partner package.
- The original PR can be found at partners, elasticsearch: Enable ElasticsearchStore to retrieve with the pure BM25 algorithm without vector search #19314.
As commented by @joemcelroy, documenting the new retrieval strategy is part of the requirements for its introduction.

Although the BM25RetrievalStrategy has been merged into langchain-elastic, its documentation is still to be maintained in the main langchain repository. Therefore, this pull request adds the documentation portion of BM25RetrievalStrategy.

The content of the documentation remains the same as that included in the original PR, #19314.

…#20098) This pull request follows up on #19314 and langchain-ai/langchain-elastic#6, adding documentation for the `ElasticsearchStore.BM25RetrievalStrategy`. Like other retrieval strategies, we are now introducing BM25RetrievalStrategy. ### Background - The `BM25RetrievalStrategy` has been introduced to `langchain-elastic` via the pull request langchain-ai/langchain-elastic#6. - This PR was initially created in the main `langchain` repository but was moved to `langchain-elastic` during the review process due to the migration of the partner package. - The original PR can be found at #19314. - As [commented](#19314 (comment)) by @joemcelroy, documenting the new retrieval strategy is part of the requirements for its introduction. Although the `BM25RetrievalStrategy` has been merged into `langchain-elastic`, its documentation is still to be maintained in the main `langchain` repository. Therefore, this pull request adds the documentation portion of `BM25RetrievalStrategy`. The content of the documentation remains the same as that included in the original PR, #19314. --------- Co-authored-by: Max Jakob <[email protected]>
