To perform a search in zcatalog in a different colums with an or =
operation,
I am joining the results lists with the following code:
    <dtml-let resa=3D"Catalog(meta_type=3D['DTML Method','ZCatalog'])"
              resb=3D"Catalog(title=3D'Song')"
              res=3D"resa[:_.len(resa)] + resb[:_.len(resb)]">
      <dtml-in res>
        A Match: <dtml-var "Catalog.getpath(data_record_id_)"><br>
      </dtml-in>
    </dtml-let>

But how can I avoid the duplicated matches of a results list from resa + =
resb ?
Regards
Marcos Iuato
