help with pear pager

Need some help here with pear's pager and I'm not sure how to proceed.

I am using the pager_wrapper_mdb2 stuff from alberton.com
(http://www.alberton.info/pear_pager_...e_results.html)
to create and display the appropriate data. i'm using javascript to
set up key trapping to page forward and backwards.

part of the requirements i'm folllowing makes it necessary to add a
text field on the page in which a user can enter a valid search string
and on exiting the field, the table should look for >= to the search
string.

what i'm getting at is that i need to be able to have the search
result (ether the correct key or the one that would logically follow)
be the first record after the search, without limiting the scope of
the paging. does that make sense?

any help is appreciated...
