How can I invert a criterion in a collection?

Honestly I don't know how this could be done (if it's possible). I'm not seeking for a development solution, i'm seeking for a solution with a plone ootb (or a plugin).

For ex. is it possible to add a criterion that excludes all contents with a specific word in the title field from results?

or is it possible to add a path criterio开发者_开发问答n that excludes all content in a specific path from results?

Doing NOT queries is not supported by ZCatalog OOTB but it can be done with AdvancedQuery. There are not add-ons that I know of that incorporate this functionality into collections for you. IOW, this would be a development task.
