the problem is not in your query-code, i guess ..

IIRC, the catalog-aware zclasses are indexed automagically
when created, but not properties you set after creation. So
when you search for track_hasfile='on' , Zcatalog doesn't
have that property indexed:

You'll have to add :
<dtml-call reindex_object> in your Zclass Constructor method
( if you change properties there)

like this :

<dtml-with "Zclass_name.createInObjectManager(REQUEST['id'], REQUEST)">
       <dtml-call "propertysheets.Propertyshhet_name.manage_editProperties(REQUEST)">
       <dtml-call reindex_object>
</dtml-with>

-
Another possibility could be that you haven't added
track_hasfile to your indexes in Zcatalog.
If it is just a on/off-flag (which it looks like from here)
, add it as a field-index..


For better information, check out the excellent Zcatalog /
catalogAware HowTos on zope.org..
