[jira] [Created] (LUCENE-4981) Deprecate PositionFilter

Adrien Grand created LUCENE-4981:
------------------------------------

             Summary: Deprecate PositionFilter
                 Key: LUCENE-4981
                 URL: https://issues.apache.org/jira/browse/LUCENE-4981
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor


According to the documentation (http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.PositionFilterFactory), PositionFilter is mainly useful to make query parsers generate boolean queries instead of phrase queries although this problem can be solved at query parsing level instead of analysis level (eg. using QueryParser.setAutoGeneratePhraseQueries).

So given that PositionFilter corrupts token graphs (see TestRandomChains), I propose to deprecate it.
