ZCatalogs have a method, 'uniqueValuesFor', which returns the set of
possible values in an index.  You might use it so (untested)::

  <select name="creator">
   <option value="" selected>Any</option>
   <option tal:repeat="uc
python:here.portal_catalog.uniqueValuesFor('Creator' )"
           tal:attributes="value uc"
           tal:content="uc">CREATOR</option>
  </select>
