Cosine distance is defined as 1 - cosine similarity, where cosine similarity measures the cosine of the angle
between two vectors in n-dimensional space: values range from 0 to 2, with 0 for identical direction, 1 for
orthogonality and 2 for opposite directions.
Only vectors of the same length are comparable, as components are matched by position: vectors of different length,
as produced by different sources, are rejected rather than reconciled.
RangeError If x and y have different lengths, if either carries a non-finite
component, or if either has a zero norm, that is if it is empty or all its components are 0
