NOT operator processing

From: Scott Schultz <scott(at)>

I'm running swish-e 2.0. For a while now, I've been having
to work around a parsing problem, so I'd like some input from
the design team as to whether this is intentional or a bug.

Briefly, if NOT is the first term of a match string then
the string will fail. If something precedes it, then it 
works fine.

For instance, the following search string fails:

(not ada) and (software or fortran)

while this one succeeds:

(software or fortran) not ada

In fact, the simple string:

not software

has to be re-written by the processing script as :

(a* or b* or c* or ... z*) not software

in order to produce any search results.

Bug or no?
