}

A CREATE VECTOR INDEX statement.

Creates an index for vector similarity search on a node property.

Syntax

CREATE VECTOR INDEX index_name ON :Label(property)
  [DIMENSION dim]
  [METRIC metric_name]

Example

CREATE VECTOR INDEX movie_embeddings ON :Movie(embedding)
  DIMENSION 384
  METRIC 'cosine'

property: String

Property containing the vector.

dimensions: Option<usize>

Vector dimensions (optional, can be inferred).

metric: Option<String>

Distance metric (default: cosine).

span: Option<SourceSpan>
