[jira] [Commented] (LUCENE-2916) QueryParser treatment of unescaped internal operators

["Jeff Evans (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-2916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15270110#comment-15270110 ] 

Jeff Evans commented on LUCENE-2916:
------------------------------------

I took a stab at the second paragraph in the description.  This is my first contribution, so any feedback is appreciated.  I first modified QueryParser.jj, then ran the javacc-QueryParser target to regenerate the parser.  I added a method to TestQueryParser to cover the change, and ensured all the tests under lucene/queryparser passed.

> myfield:foo-bar and myfield:foo+bar are treated as myfield:"foo-bar" and myfield:"foo+bar"
> but myfield:foo!bar is treated as myfield:foo -defaultfield:bar
> Somewhat related, temp:70 works fine, but temp:-10 throws an exception.  Many people hit this and figure out how to work around it relatively quickly, but just fixing the grammar to accept it might be better?
