Pagination and Search

[eluser]danish[/eluser]
Hi,
I am using a search function and search has three fields. User can enter any combination of these fields and search the database. Now I pagination to search results. But I am very confused how to do this. The main concern is how to send the three fields which search the database. I have turned on the query string but is shows me this error.


Disallowed Key Characters.

So please guide me how can I solve this issue.
Thanks
