FAQPage Schema
How do I build a vector index for semantic search from a directory of files?

Build a vector index for semantic search by targeting a specific directory and naming the resulting LEANN-powered index. This process creates a searchable graph-based structure for rapid information retrieval.

Can I add new content to an existing semantic search index incrementally?

Yes, you can add new content to an existing semantic search index incrementally. This feature allows continuous updates to the LEANN-powered vector index without rebuilding it from scratch.

How does a graph-based vector index reduce storage for semantic search?

Graph-based vector indexes reduce storage for semantic search by using LEANN techniques to structure the data efficiently. This approach minimizes the storage footprint compared to traditional flat vector indexes.

How do I check the health of a LEANN-powered vector index?

Check the health of a LEANN-powered vector index to ensure it is functioning correctly for semantic search. This diagnostic process verifies the structural integrity and search readiness of the index.

Can I query a vector index directly via gRPC for semantic search?

Yes, you can query a vector index directly via a gRPC service for semantic search. This allows rapid and accurate retrieval of information from the indexed content over the network.
