Hm, do you have 2 problems?

  1.  a KeyError
  2.  an unexpected search result

The "title" field in your catalog's "Meta Data Table" is resolved into
a DTML Method (named "title") for at least one of the objects
to be catalogued.
This DTML Method references a variable "question" which is not
defined in the current context.

It is not a good idea, to name a DTML Method "title".

Your second problem:

That is strange (and should not happen).

Apparently, the "portal_catalog" does not see the "Type" in the
REQUEST. You are sure, it is there?
