Subject [jira] [Commented] (SOLR-3580) In ExtendedDismax, lowercase 'not' operator is not being treated as an operator when 'lowercaseOperators' is enabled
Date Wed, 03 Apr 2013 12:31:19 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13620889#comment-13620889
] 

Jan Høydahl commented on SOLR-3580:
-----------------------------------

Any progress on this?

A more compact config format would be possible too:
{code}
validOperators=or:OR,or and:AND,and not:NOT
{code}

Then, if we add more operators later, such as NEAR, the same param would apply. Perhaps we
also could use this to disable explicit operators alltogether by allowing an empty list {{validOperators=or:
and: not:}} - for people who want to lock things down.

As for interaction with lowercaseOperators, I'm happy to let it hang around for 4.x, but throw
an exception if both params are defined together.

> 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).
