Description

Afaics, the fulltext grammar spec [0] allows a stand-alone hyphen to be a simple word.

So, it seems all of these are valid:

1. A - B //hyphen being a separate word
2. A - //hyphen being a separate word at the end
3. A -B //hyphen working as negation operator on B
4. A -"B C" //hyphen working as negation operator on "B C"

Currently, case 1 and 2 are treated as invalid.
