Tomaz Bratanic	7d25a65b10	add from_existing_graph to neo4j vector (#11124) ... This PR adds the option to create a Neo4jvector instance from existing graph, which embeds existing text in the database and creates relevant indices.	2023-09-28 15:02:26 -07:00
Tomaz Bratanic	e1e01d6586	Add Neo4j vector index hybrid search (#10442) ... Adding support for Neo4j vector index hybrid search option. In Neo4j, you can achieve hybrid search by using a combination of vector and fulltext indexes. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	2023-09-14 08:29:16 -07:00
Tomaz Bratanic	db13fba7ea	Add neo4j vector support (#9770) ... Neo4j has added vector index integration just recently. To allow both ingestion and integrating it as vector RAG applications, I wrapped it as a vector store as the implementation is completely different from `GraphCypherQAChain`. Here, we are not generating any Cypher statements at query time, we are simply doing the vector similarity search using the new vector index as if we were dealing with a vector database. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	2023-08-29 07:54:20 -07:00
