Subject [jira] [Commented] (SOLR-3580) In ExtendedDismax, lowercase 'not' operator is not being treated as an operator when 'lowercaseOperators' is enabled
Date Tue, 31 Jul 2012 15:45:35 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13425853#comment-13425853

Jack Krupansky commented on SOLR-3580:
--------------------------------------

I'm okay with the proposal for "supportedLowercaseOperators", but I would make two points:

1. What about mixed case? Would mixed case And/Or/Not be treated as lower case? Or only strict
lower case?
2. How about a revised compromise - Keep "lowercaseOperators=true/false" as is for compatibility,
but also support the same parameter name with the form "lowercaseOperators=and,or,not" to
provide the desired flexibility. All the benefit of the current proposal, but without the
need to switch/deprecate the old form.

> 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).
