Incorrect results: "(expression1) AND NOT (expression2)" #15

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago

Occasionally queries of the pattern : 
"expression1 AND NOT expression2" 
give incorrect results for complex expressions.

All versions of dpsearch upto 4.53 snapshots.

Gut feeling is that the parser fails and treats AND or NOT as regular words
rather than as the boolean operators in some situation.

The parser treats AND and NOT (and any other operator name) as a regular words 
when
they are enclosed by single (') or double (") quotes. Could you, please provide 
some
examples of requests that been treated incorrectly ?
