[jira] Commented: (SOLR-1658) Negative query weirdness

["Yonik Seeley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12790930#action_12790930 ] 

Yonik Seeley commented on SOLR-1658:
------------------------------------

I agree.  Extended dismax already implements this.

It comes down to needing a flag... sometimes you want pure negative queries (when parsing query parts for example) and sometimes you don't.  We should just add a boolean flag to SolrQueryParser.

*But* we don't want to do this for the top level for filter queries - as an optimization, solr currently caches -foo:x the same as foo:x and if we always handled negative queries at the QP level, it would disable that.

> In the standard Solr example, the queries
> # adapter AND NOT power
> # adapter AND (NOT power)
> are different.  The second will never return any results.  I find this surprising.  I think the second query should be the same as the first.
