yeah . Just chk the behaviour of the website like when you search anything, is the url contains the keyword "you have used" then the simple way is to generate querystring. Otherwise open the webpage's source code and find the form action and then create your own page use the same action page with same variables which were used in original page.
For the querystring you have to study the URL passed after search. If still problem is there. copy paste the URL here in the board. We will see how can we help you.
