 supersedes the order_by stage. If multiple documents have the same vector
 distance, the returned document order is not guaranteed to be stable
 between queries.

       Optional. Option to specify a threshold for which no less similar
       documents will be returned. The behavior of the specified

       Since DOT_PRODUCT distances increase when the vectors are more similar,
       the comparison is inverted.
