    [ https://issues.apache.org/jira/browse/LUCENE-2566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13465361#comment-13465361 ] 

Andrew Gibb commented on LUCENE-2566:
-------------------------------------

This is great!

There seems to be an inconsistency with the exclamation mark ! (NOT operator)

"foo-" acceptable
"foo+" acceptable
"foo!" parse exception

although if I add whitespace after: 

"foo! " acceptable

Is this expected operation? Am I missing something

> As an example, (foo - bar) is treated like (foo -bar).
> It seems like for +- to be treated as unary operators, they should be immediately followed by the operand.
