[jira] [Commented] (SOLR-3315) SOLR ignores 'NOT' clause in query

["Tom Marsh (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246603#comment-13246603 ] 

Tom Marsh commented on SOLR-3315:
---------------------------------

Further investigation has shown that inverting the rule with de Morgans: -(-FirstName_s:"Bob" AND Department_t:"Ninjas") does give us the result we expected. However, I believe this points to this being a parsing bug.

>             Project: Solr
>          Issue Type: Bug
>          Components: search
>    Affects Versions: 3.5
>         Environment: Windows, Java 7
>            Reporter: Tom Marsh
>            Priority: Critical
>              Labels: not, query
>
> We have a simple domain where
> FirstName_s:"Bob"
> returns 40 documents, and
> -Department_t:"Ninjas"
> returns all of the documents (we don't have a ninja department).
> We expected the query
> (FirstName_s:"Bob") OR (-Department_t:"Ninjas")
> to return all documents, however it only returned the original 40 documents.
> We have experimented with a couple of different orderings, tried using 'NOT' instead of '-' all to no avail.
> Is this expected behavior? Perhaps more importantly, how do we get the behavior we expect?
