problem with scrollbar position

i have a unique problem with scrollbar. Actually i am searching for some values and since the list is huge i am displaying using a scrollbar, here i am dragging the scroll bar down and with out dragging the scrollbar again back to top i am clicking on the search again. The problem is the scroll bar is positioned at the bottom itself. I want the scrollbar to be coming back to the normal position i.e. top position.

please let me know how to solve this. I am using JScrollPane.
