[Zope] Object propogation

[David Mackay]

I'm trying to filter the results of a Zsearch, and return the filtered 
results to the user.  I have an external python script which queries a 
textindex, and returns a list of mybrain objects.  I can then build a 
new list with the filtered results, and return that to the dtml method 
which displays the first 20 results with no problem.  I copied the dtml 
method generated by an add Z Search Interface, and modified it to 
process the filtered list.  The problem is that I can't get it to handle 
the next 20 (and so on) results.  The Fresults list that I process the 
first time doesn't propogate to the next iteration.  The results list 
obviously DO propogate for the unaltered search forms.  Does anyone have 
any suggestions?
