[Zope] total "hits" in dtml-in?

I've just put together my first Zope/MySQL database search interface.
Gosh that's cool. However, I have a question. Obviously.
How can I get the _total_ number of returned results for a <dtml-in>
statement (not the number in the current batch)? This is probably so
obvious that it's staring me in the face, but I can't find it anywhere.
I even tried (quickly) perusing some source code, but maybe I was
looking in the wrong place. My main reference has been the Zope book,
another Zope book, and searching the web site.
I know about the cool dtml-in variables like
previous-sequence-start-index, next-sequence-size, etc., but I want to
be able to state on my results form "records 21-40 of X shown" - how do
I gracefully get X? I know I could do a len() of the query, but that
seems like a bad idea because the database would essentially get queried
twice - once to get the len, and once to create the <dtml-in> list.
Right? Am I missing something? Of course I am. Any help would be much
