Inside the code generated by the zope search interface dtml result page
a batch variable 'query' is used in Zope 2.7.6. This gives a key error
when having next and previous batches. It also seems to be used in the
ZSQL methods query template because the same error occurs there when
having more than 20 results (the batch value). Does anybody know about
this? In the dtml template it is easy to change, but I can't do much
about the ZSQL template.
