Lage Ragnarsson	a3c10fc6ce	community: Add support for specifying hybrid search for Databricks vector search (#23528 ) Description: Databricks Vector Search recently added support for hybrid keyword-similarity search. See [usage examples](https://docs.databricks.com/en/generative-ai/create-query-vector-search.html#query-a-vector-search-endpoint) from their documentation. This PR updates the Langchain vectorstore interface for Databricks to enable the user to pass the query_type parameter to similarity_search to make use of this functionality. By default, there will not be any changes for existing users of this interface. To use the new hybrid search feature, it is now possible to do ```python # ... dvs = DatabricksVectorSearch(index) dvs.similarity_search("my search query", query_type="HYBRID") ``` Or using the retriever: ```python retriever = dvs.as_retriever( search_kwargs={ "query_type": "HYBRID", } ) retriever.invoke("my search query") ``` --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com> Co-authored-by: Erick Friis <erick@langchain.dev>	2 months ago

JP-Ellis	f77659463a	core[patch]: allow message utils to work with lcel (#23743 ) The functions `convert_to_messages` has had an expansion of the arguments it can take: 1. Previously, it only could take a `Sequence` in order to iterate over it. This has been broadened slightly to an `Iterable` (which should have no other impact). 2. Support for `PromptValue` and `BaseChatPromptTemplate` has been added. These are generated when combining messages using the overloaded `+` operator. Functions which rely on `convert_to_messages` (namely `filter_messages`, `merge_message_runs` and `trim_messages`) have had the type of their arguments similarly expanded.
