["Varun Thacker (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-8089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14933173#comment-14933173 ] 

Varun Thacker commented on SOLR-8089:
-------------------------------------

{{QueryParserBase#setEnablePositionIncrements}} will ignore holes in the query token stream . We need some sort of support at indexing time as well here for it to match.

> In 5.0 LUCENE-4963 disallowed setting enablePositionIncrements=false on any token filter. The idea being no filter should change the token stream in a way that could mess up preceding or following analysis components
> So if a user wants to be able to have PhraseQueries that match across stopwords they cannot unless the parser is configured to not take position increments into account when generating phrase queries .
> This is documented in the "Token Position Increments" section here : https://lucene.apache.org/core/5_3_0/core/org/apache/lucene/analysis/package-summary.html
