For a worklist, that criterion is not even appropriate:  worklists could
quite reasonably contain content which is either not yet effective, or
which has expired.

The general case could be made a great deal more efficient by using a
DateRange index.  I don't think we yet add one by default to the CMF's
catalog: 'effective_range' would be a good name;

A worklist query would benefit from a dedicated TopicIndex, as well.
