---------------

      This form consists of three input boxes named *content*,
      *author*, and *date*.  These names of the input form elements
      match the names of the indexes in the catalog. These names must
      match the names of the catalog's indexes for the catalog to find
      the search terms.  Here is a report form that works with the
      search form::

        <dtml-var standard_html_header>

        <table>
          <dtml-in NewsCatalog>
          <tr>
            <td><dtml-var author></td>
            <td><dtml-var date></td>
          </tr>
          </dtml-in>
        </table>

        <dtml-var standard_html_footer>

         Again you managed to give a teriffic example. This doesn't do anything but to list what you have typed in for
         author and date in the 'form'.
         And even more: It does so for each object that is in your catalog.
         What did you want to explain, here?
         I mean, if one has come so far, he/she should be at a point where he/she understands how the in-loop works
         ... and there isn't anything else you can learn from this example, is there??

         this works if you want to look for a 
         object containing the data AND author.
         but what about if you want to search in the catalog
         looking for data OR author ???
