Introducing ToolsRetriever in the Neo4j GraphRAG Python Package

Neo4j GraphRAG Python library introduces ToolsRetriever class and convert_to_tool() method, enabling dynamic LLM-driven selection of multiple retrievers as tools. This allows combining different retrieval strategies like VectorRetriever for semantic search and Text2CypherRetriever for structured queries, with the LLM intelligently choosing the most appropriate tool(s) for each query. The feature maintains compatibility with existing GraphRAG workflows while providing flexibility for hybrid retrieval approaches.
