Static Fields
Name	Description
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 to learn more about COSINE similarity and COSINE distance. The resulting COSINE distance decreases the more similar two vectors are. COSINE = 2;
COSINE_VALUE	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 to learn more about COSINE similarity and COSINE distance. The resulting COSINE distance decreases the more similar two vectors are. 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. The resulting distance increases the more similar two vectors are. DOT_PRODUCT = 3;
DOT_PRODUCT_VALUE	Similar to cosine but is affected by the magnitude of the vectors. See Dot Product to learn more. The resulting distance increases the more similar two vectors are. DOT_PRODUCT = 3;
EUCLIDEAN	Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more. The resulting distance decreases the more similar two vectors are. EUCLIDEAN = 1;
EUCLIDEAN_VALUE	Measures the EUCLIDEAN distance between the vectors. See Euclidean to learn more. The resulting distance decreases the more similar two vectors are. EUCLIDEAN = 1;
