      Querying a ZCTextIndex with these advanced features works just
      like querying it with the original simple features.  In the HTML
      search form for DTML Documents, for example, you could enter
      "Koala AND Lion" and get all documents about Koalas and Lions.
      Querying a ZCTextIndex from Python with advanced features works
      much the same; suppose you want to change your
      'relevantSectionNews' Script to not include any news items that
      contain the word "catastrophic"::

        ## Script (Python) "relevantSectionNews"
        ##
        """ Returns relevant, non-catastropic news """"
        id=context.getId()
        return context.NewsCatalog(
                 {'contentTextIdx' : id + ' -catastrophic'}
                )

         Little error:

         """ Returns relevant, non-catastropic news """"
         ... should be ...
         """ Returns relevant, non-catastropic news """

         or even better:
         """ Returns relevant, non-catastrophic news """
