Create Vector Index #4

Closed ThanhNguye-n closed 5 months ago

ThanhNguye-n commented 5 months ago

Hi,

Seem the syntax for creating node vector index is deprecated: CALL db.index.vector.createNodeIndex('chunkVectorIndex', 'Embedding', 'value', 1536, 'COSINE')

ClientError: {code: Neo.ClientError.Procedure.ProcedureNotFound} {message: There is no procedure with the namedb.index.vector.createNodeIndexregistered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.}

Any update on this syntax and which version of Neo4j and Database you using ? AuraDB or GraphDS ? Thanks in advance.
