You need to pass your old parameters.

You have (at least) two options:

  * you use "GET" requests (which is appropriate for searches).

    Then the parameters to your request are in "QUERY_STRING".

    You may need to strip out your sorting parameters (using 'replace')
    (or use my ":last" path on 
      <http://www.dieter.handshake.de/pyprojects/zope>)
    in order not to get your parameters piled up.

  * you use the "make_query" (or something similar) in
    "ZTUtils" to build your parameters.

For both cases, you can get intuition from a batching example (I
expect, you find some in the Zope Book).
