[Zope] Restricting the size of results returned by the Catalog

Hi, Is there a parameter you can pass to the catalog in a query to return the results as soon as a maximum results size is reached? Rather than the catalog returning say 3000 results and you want to restrict results to the first 500? I'm running zope 2.5.1, python 2.1.3, testing on win2000. Thanks for any help.
