Firestore v1 API - Enum StructuredQuery.Types.FindNearest.Types.DistanceMeasure (3.8.0)

public enum StructuredQuery.Types.FindNearest.Types.DistanceMeasure

Reference documentation and code samples for the Firestore v1 API enum StructuredQuery.Types.FindNearest.Types.DistanceMeasure.

The distance measure to use when comparing vectors.

Namespace

Assembly

Fields

Name Description
Cosine

Compares vectors based on the angle between them, which allows you to measure similarity that isn't based on the vectors magnitude. We recommend using DOT_PRODUCT with unit normalized vectors instead of COSINE distance, which is mathematically equivalent with better performance. See Cosine Similarity to learn more.

DotProduct

Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more.

Euclidean

Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more

Unspecified

Should not be set.
