That should be straightforward:  add a "String Criterion" for
"Subject" on the "Criteria" page of the topic.

So the way I'd like to solve this is to have a query that builds a list of
existing subject keywords.  Then have the user click on one to fire another
query that lists all objects that have that subject in their metadata.  I
have the method that lists all the subjects (SubjList) and I have a method
that can list the details of a subject (SubjDetl).  My question is how do I
pass the 'subject' that the user clicked on.

SubjList:
  <dtml-in expr="portal_catalog.uniqueValuesFor( 'Subject' )" >
    <a href=SubjDetl>&dtml-sequence-item; </a><br>
  <dtml-else>
    No subjects
  </dtml-in>

SubjDetl
  <dtml-in "portal_catalog.searchResults( Subject=  <<<need to know how I
pass info here>>>
    , sort_on='Date'
    , sort_order='reverse'
    , review_state='published'
    )" size="10">
    <tr class="SubjDetlItemRow">
      <td valign="top">
        <a href="<dtml-var "getURL()">"> &dtml-Title; </a><br>
        &dtml-Date;<br>
      </td>
    </tr>
  <dtml-else>
    <tr class="SubjDetlItemRow">
      <td valign="top">
        There are no details.
      </td>
    </tr>
  </dtml-in>


Thanks,
