Subject [jira] [Created] (LUCENE-8315) Make FeatureField easier to use

------------------------------------

             Summary: Make FeatureField easier to use
                 Key: LUCENE-8315
                 URL: https://issues.apache.org/jira/browse/LUCENE-8315
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


I'd like to do some changes to FeatureField so that when the saturation function is used and
the pivot should be computed automatically from index statistics, then things also work as
expected with distributed term frequencies. It works by returning the feature term in extractTerms.

As a side-effect, no need to provide the IndexSearcher when creating the query anymore, it
is autamatically picked up at rewrite time, which makes it nicer to use too.
