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

Unspecified
Should not be set.
