Subject [jira] [Commented] (SOLR-8089) Support query parsers being able to set enablePositionIncrements
Date Wed, 29 Nov 2017 05:47:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-8089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16270190#comment-16270190
] 

David Smiley commented on SOLR-8089:
------------------------------------

I think query time is not enough; wouldn't we need to adjust the index analysis to posInc=1
too?  Otherwise index data of "foo the bar" would not be found by the query "foo bar" (and
we want it to if a user wants enablePositionIncrements=false)

disclaimer: I didn't look at the patch

p.s. recent discussion here: https://issues.apache.org/jira/browse/LUCENE-8036?focusedCommentId=16270188&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16270188

> 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
