Re: [Zope-dev] NOT operator in Unindex.

For example, I like very much, that my ManagableIndexes do not index objects whose value (with respect to the index) is None (or matched by the ignore predicate). Such indexes do not have enough information to implement NOT by themselves (they would need the set of all catalogued objects from the catalog). I would not implement NOT at the index level (as I would not implement AND or OR at this level). All logical operators should be implemented by the search engine and not by the individual indexes. -- Dieter ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

My exampel extends Field- and KeywordIndex and any other index based on Unindex without changing backward compatability. I don't see a reason why this couldn't be included to the Zope Core in a short term.
