Implemented: New switch for search to perform an AND NOT search
A regular expression search already supports an AND search with a
";" delimiter, like
"soap;web service". This new enhancement allows you to perform an AND NOT search with a
"!" prefix in the search token, e.g.
"soap;web service;!shampoo" will search for
"soap" AND
"web service" AND NOT
"shampoo".

could we replace the ; and ! with
- [Aa][Nn][Dd]
- [Nn][Oo][Tt]
and then add
so that we eventualliy go towards the same syntax as Google?

This is just for the regex search.
KeywordSearchWithImplicitAnd will support syntax:
soap +wsdl "web service" -shampoo, which gets translated internally into a regex search:
soap;wsdl;web service;!shampoo
This feature is now in
TWikiAlphaRelease and at TWiki.org.
