Create and query vector indexes

Use HNSW vector indexes for Approximate Nearest Neighbor (ANN) search.

Usage

Create vector indexes with specific dimension and similarity configurations, then query them using db.idx.vector.queryNodes.

Example

redis-cli GRAPH.QUERY social "CREATE VECTOR INDEX FOR (p:Product) ON (p.embedding)
OPTIONS {dimension: 768, similarityFunction: 'cosine', M: 32, efConstruction: 200}"

redis-cli GRAPH.QUERY social "CALL db.idx.vector.queryNodes('Product', 'embedding', 5, vecf32([0.1, 0.2, 0.3]))
YIELD node, score RETURN node.name, score"

Notes

Vector indexes use HNSW (Hierarchical Navigable Small World) algorithm
Configure dimension to match your embedding size
Similarity functions include 'cosine', 'euclidean', etc.
M and efConstruction parameters tune index performance and accuracy
Use vecf32() to pass vector values in queries
Returns nodes with their similarity scores
