Shotaro Sano	6c11c8dac6	docs: Add documentation of `ElasticsearchStore.BM25RetrievalStrategy` (#20098) ... This pull request follows up on https://github.com/langchain-ai/langchain/pull/19314 and https://github.com/langchain-ai/langchain-elastic/pull/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 https://github.com/langchain-ai/langchain-elastic/pull/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 https://github.com/langchain-ai/langchain/pull/19314. - As [commented](https://github.com/langchain-ai/langchain/pull/19314#issuecomment-2023202401) 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, https://github.com/langchain-ai/langchain/pull/19314. --------- Co-authored-by: Max Jakob <max.jakob@elastic.co>	3 months ago

Marlene	2f03bc397e	Community: Updating Azure Retriever and Docs to be Azure AI Search instead of Azure Cognitive Search (#19925) ... Last year Microsoft [changed the name](https://learn.microsoft.com/en-us/azure/search/search-what-is-azure-search) of Azure Cognitive Search to Azure AI Search. This PR updates the Langchain Azure Retriever API and it's associated docs to reflect this change. It may be confusing for users to see the name Cognitive here and AI in the Microsoft documentation which is why this is needed. I've also added a more detailed example to the Azure retriever doc page. There are more places that need a similar update but I'm breaking it up so the PRs are not too big 😄 Fixing my errors from the previous PR.
