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.
