LangGraph has introduced semantic search to its BaseStore, enhancing the capabilities of its memory support by allowing retrieval of information based on meaning rather than exact matches. This feature is now available in both the PostgresStore and InMemoryStore, as well as in the LangGraph studio and all LangGraph Platform deployments. Semantic search addresses user demands for more sophisticated retrieval of unstructured information by enabling agents to recall user preferences, learn from past interactions, and maintain consistent knowledge. The implementation involves configuring the server to embed new items through a store configuration, with options to customize embedding logic and specify fields to index. This update is non-breaking for existing users, and LangGraph has provided updated documentation and templates to assist users in integrating semantic search into their workflows.
