[Zope-DB] key error on query variable in previous and next batches

[Henk Laloli]

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.
