 For each configured <<dense-vector-similarity, similarity>>, here is the corresponding inverted `_score` function. This is so if you are wanting to filter from a `_score` perspective, you can do this minor transformation to correctly reject irrelevant results.

 Here is an example. In this example we search for the given `query_vector` for `k` nearest neighbors. However, with
