[jira] [Updated] (LUCENE-7347) Remove queryNorm and coords

     [ https://issues.apache.org/jira/browse/LUCENE-7347?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adrien Grand updated LUCENE-7347:
---------------------------------
    Summary: Remove queryNorm and coords  (was: Remove queryNorm and disableCoord)

> Remove queryNorm and coords
> ---------------------------
>
>                 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.
