Rafael Pereira	cf28708e7b	Neo4j: Update with non-deprecated cypher methods, and new method to associate relationship embeddings (#23725 ) Description: At the moment neo4j wrapper is using setVectorProperty, which is deprecated ([link](https://neo4j.com/docs/operations-manual/5/reference/procedures/#procedure_db_create_setVectorProperty)). I replaced with the non-deprecated version. Neo4j recently introduced a new cypher method to associate embeddings into relations using "setRelationshipVectorProperty" method. In this PR I also implemented a new method to perform this association maintaining the same format used in the "add_embeddings" method which is used to associate embeddings into Nodes. I also included a test case for this new method.	2 months ago

Rafael Pereira	fc41730e28	neo4j: Fix test for order-insensitive comparison and floating-point precision issues (#24338 ) Description: This PR addresses two main issues in the `test_neo4jvector.py`: 1. Order-insensitive Comparison: Modified the `test_retrieval_dictionary` to ensure that it passes regardless of the order of returned values by parsing `page_content` into a structured format (dictionary) before comparison. 2. Floating-point Precision: Updated `test_neo4jvector_relevance_score` to handle minor floating-point precision differences by using the `isclose` function for comparing relevance scores with a relative tolerance. Errors addressed: - test_neo4jvector_relevance_score: ``` AssertionError: assert [(Document(page_content='foo', metadata={'page': '0'}), 1.0000014305114746), (Document(page_content='bar', metadata={'page': '1'}), 0.9998371005058289), (Document(page_content='baz', metadata={'page': '2'}), 0.9993508458137512)] == [(Document(page_content='foo', metadata={'page': '0'}), 1.0), (Document(page_content='bar', metadata={'page': '1'}), 0.9998376369476318), (Document(page_content='baz', metadata={'page': '2'}), 0.9993523359298706)] At index 0 diff: (Document(page_content='foo', metadata={'page': '0'}), 1.0000014305114746) != (Document(page_content='foo', metadata={'page': '0'}), 1.0) Full diff: - [(Document(page_content='foo', metadata={'page': '0'}), 1.0), + [(Document(page_content='foo', metadata={'page': '0'}), 1.0000014305114746), ? +++++++++++++++ - (Document(page_content='bar', metadata={'page': '1'}), 0.9998376369476318), ? ^^^ ------ + (Document(page_content='bar', metadata={'page': '1'}), 0.9998371005058289), ? ^^^^^^^^^ - (Document(page_content='baz', metadata={'page': '2'}), 0.9993523359298706), ? ---------- + (Document(page_content='baz', metadata={'page': '2'}), 0.9993508458137512), ? ++++++++++ ] ``` - test_retrieval_dictionary: ``` AssertionError: assert [Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nname: John\nage: 30\n')] == [Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nage: 30\nname: John\n')] At index 0 diff: Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nname: John\nage: 30\n') != Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nage: 30\nname: John\n') Full diff: - [Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nage: 30\nname: John\n')] ? --------- + [Document(page_content='skills:\n- Python\n- Data Analysis\n- Machine Learning\nage: John\nage: 30\n')] ? +++++++++ ```	2 months ago

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.
