["Adrien Grand (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-6531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adrien Grand updated LUCENE-6531:
---------------------------------
    Attachment: LUCENE-6531.patch

Here is a patch. PhraseQuery has a main constructor: PhraseQuery(int slop, String field, List<TermAndPosition> termsAndPositions) and some sugar constructors such as PhraseQuery(String field, String... terms) that will search for terms at consecutive positions in {{field}} with a slop of 0.

> Mutable queries are an issue for automatic filter caching since modifying a query after it has been put into the cache will corrupt the cache. We should make all queries immutable (up to the boost) to avoid this issue.
