Hi all,
Well, I've had a look at QueryParser.jj and not being familiar with javacc
etc I can now safey say I'm a bit brain-fried.
Having thought more about it, it would be cool to be able to escape any of
the "special" chars - []{}() etc. Someone care to point me in the right
direction and I'll have a go.
Rgds,
Les
