[jira] [Created] (LUCENE-7347) Remove queryNorm and disableCoord

Adrien Grand created LUCENE-7347:
------------------------------------

             Summary: Remove queryNorm and disableCoord
                 Key: LUCENE-7347
                 URL: https://issues.apache.org/jira/browse/LUCENE-7347
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand


These two features are specific to TF-IDF and introduce some complexity (see eg. handling of coords in BooleanWeight) and bugs/corner-cases (see eg. how taking the query norm into account causes scoring challenges on LUCENE-7337).

Since we made BM25 the default in 6.0, I propose that we remove these TF-IDF-specific features in 7.0.
