Interface IRankFeatureQuery

A query that only works on rank_feature fields and rank_features fields. Its goal is to boost the score of documents based on the values of numeric features. It is typically put in a should clause of a bool query so that its score is added to the score of the query.

Compared to using function_score or other ways to modify the score, this query has the benefit of being able to efficiently skip non-competitive hits when track_total_hits is not set to true. Speedups may be spectacular.
