[jira] [Created] (LUCENE-8311) Leverage impacts for phrase queries

Adrien Grand created LUCENE-8311:
------------------------------------

             Summary: Leverage impacts for phrase queries
                 Key: LUCENE-8311
                 URL: https://issues.apache.org/jira/browse/LUCENE-8311
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand


Now that we expose raw impacts, we could leverage them for phrase queries.

For instance for exact phrases, we could take the minimum term frequency for each unique norm value in order to get upper bounds of the score for the phrase.
