Static 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. COSINE = 2;
COSINE_VALUE	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. COSINE = 2;
DISTANCE_MEASURE_UNSPECIFIED	Should not be set. DISTANCE_MEASURE_UNSPECIFIED = 0;
DISTANCE_MEASURE_UNSPECIFIED_VALUE	Should not be set. DISTANCE_MEASURE_UNSPECIFIED = 0;
DOT_PRODUCT	Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more. DOT_PRODUCT = 3;
DOT_PRODUCT_VALUE	Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more. DOT_PRODUCT = 3;
EUCLIDEAN	Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more EUCLIDEAN = 1;
EUCLIDEAN_VALUE	Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more EUCLIDEAN = 1;
