DistanceMeasure(value)

The distance measure to use when comparing vectors.

Enums
Name	Description
DISTANCE_MEASURE_UNSPECIFIED	Should not be set.
EUCLIDEAN	Measures the EUCLIDEAN distance between the vectors. See `Euclidean
COSINE	COSINE distance 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
DOT_PRODUCT	Similar to cosine but is affected by the magnitude of the vectors. See `Dot Product
