How to search "ActiveDocs" in folder-level script

Question

I am trying to perform a search in an Acrobat folder-level javascript like this:
     function timerCallback() {
          app.beginPriv();
          search.query(searchText, "ActiveDoc");
          app.endPriv();
     app.beginPriv();
     app.openDoc(path_to_my_doc);
     app.endPriv();
     app.setTimeOut("timerCallback()", 5000);
I use the setTimeOut function to make sure that the document has had enough time to open before I start the search.  The problem is that I get this error:
          GeneralError: Operation failed.
          Search.query:24:Folder-level:App:SearchScript.js
          No active document
It seems like I can't "see" active documents from a folder-level script.  Is there any way around this?
Thanks

A folder-level script can be used for two things:
- Execute commands relevant to the application as a whole, NOT dependent of
any specific document (e.g. adding new menu items).
- Create functions which should be available to any document or script that
might need them (e.g. formatting a string in a certain way).
What you're trying to do is neither here nor there. If you want to be able
to search existing documents, you can use a folder-level function, but then
you need to call it from somewhere else, like a menu item or a toolbar
button.
