[jira] [Commented] (SOLR-3580) In ExtendedDismax, lowercase 'not' operator is not being treated as an operator when 'lowercaseOperators' is enabled

    [ https://issues.apache.org/jira/browse/SOLR-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13753788#comment-13753788 ] 

Eric Pugh commented on SOLR-3580:
---------------------------------

I was about to submit a patch for the fact that 'NOT' and 'not' don't work the same, when I stumbled across this issue.  My patch file looks rather remarkably like [~mdodsworth@salesforce.com] first patch as well!    

One thing is that the wiki needs an update: http://wiki.apache.org/solr/ExtendedDisMax#lowercaseOperators   I can put that in, referring to the patch files as option if you need not:NOT support.

I would like to see something committed, as my customer has the same need for NOT to work.   Their users are sophisticated, know the syntax etc.   Backup plan is to do something custom.

> When lowercase operator support is enabled (for edismax), the lowercase 'not' operator is being wrongly treated as a literal term (and not as an operator).
