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".

This is in preparation of the KeywordSearchWithImplicitAnd feature.

could we replace the ; and ! with

• [Aa][Nn][Dd]
• [Nn][Oo][Tt]

• [Oo][Rr]

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.
