The CMF already has a "keywords" field, 'Subject' (the name
comes fromt the Dublin Core).  I would build a keyword-based
search something like:

 <form action=3D"&dtml-portal_url;/search">

  <select name=3D"Subject">
   <dtml-in "portal_catalog.uniqueValuesFor( 'Subject' )">
    <option> &dtml-sequence-item; </option>
   </dtml-in>
  </select>

  <input type=3D"submit" value=3D" Search ">

 </form>

The new "PortalTopic" objects are still somewhat under
development;  they allow you to create an object which
represents a "canned" catalog query.

You shouldn't need "Wizards" to make them;  you should
already be able to add them using the Zope Management
interface, and then add "criteria" objects to them to
represent the search.  They should have a great deal
more documentation over the next few weeks.
