It will be easily reproducible...

It seems extremely difficult to include the search in the generated
links. Even the Zope core contains bugs in this respect at
two places.

As you can easily see, this (and the next) link does not include

The "ZTUtils" package contains a method "make_query" that allows you
to fix this bug.

Currently, I do not have time to provide the code.
Come back, when you need more help.
