[CPS-devel] zctextindex: everything except 'some words'

[Florent Guillaume]

Yes, ZCTextIndex only allows NOT when preceded by AND. Really,  
operators are OR, AND and AND NOT.
Also super-wildcards are disallowed by the code.
You could change globToWordIds in lib/python/Products/ZCTextIndex/ 
Lexicon.py to allow for them.
