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.
`DOT_PRODUCT`	Similar to cosine but is affected by the magnitude of the vectors.
`EUCLIDEAN`	Measures the EUCLIDEAN distance between the vectors.
