Hey Chris, You are a life saver (like many times before). It works like a charm. Thanks, BZ On Mon, 7 May 2001 16:44:26 -0400, "Chris McDonough" <chrism@digicool.com> wrote :

Hi BZ,

Assuming field_name is a field index, try:

<dtml-in "searchResults(field_name=[''])" size="5" start=query_start> ... </dtml-in>

For the ugly reasons why this is necessary, see the docstring of the _apply_index method of the UnIndex class within lib/python/SearchIndex/UnIndex.py .

...

I want to search through a ZCatalog and only return things that have an empty field.

...

From everything I have read, this should work

<dtml-in "searchResults(field_name='')" size="5" start=query_start> .... </dtml-in>

but it does not...

Anyone?

BZ
