RAG frame work using vector database and neo4j graphs

I want to develop a nlp applicaiton using vector database and neo4j graphs. I see a lot of developing apps using them. is there a open source code, which works as a frame work so that I can just create vector database without creating code from scratch.

For Vector Database, use either pinecone or milvus. Milvus is opensource.

For integration, use Python Programming Language and to interact with neo4j, use Py2neo.

Let me know if it answers your question.
