... batched "next" does not work ... It does complain that the ContentText (the textindex) is not present for the subsequent requests. I can get it to re-execute for subsequent requests by passing that in the url. Since I'm searching a rather large record set, I was hoping to avoid the repetition of the search. I tried saving the returned list in the session data, but I got a traceback saying that the object was unpickleable.

Do you have any suggestions as to how to preserve the list of mybrains objects so that I can access that, rather than re-executing the query? You cannot preserve the sequence of "mybrain" objects, but you can store their record ids and resolve the ids later into the objects by means of a catalog method.

For details, please read the "ZCatalog" section of <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html> It tells you the exact name of the record id and the name of the catalog method. You are probably also interested in Pythons "list comprehension": [x.record_id_ for x in catalog(...)] Dieter PS: Please stay on the list.
