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
> + - operators allow any amount of whitespace

> 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.
