Customize Magento

Hi All! I have a custom coded, product addition tool. I am looking to make it so that the search listed on this page is persistant, after editing or adding products. As an example, I can search for "linking rings" and then click EDIT and make changes or add products. When I hit SAVE at the bottom or NEW PRODUCT the term "linking rings" is still held and the results still displayed until RESET FILTER is clicked. In it's current state, if the user wanted to edit many linking ring entries, the user hits save,and then other random products are shown. The search should be "persistant" so that all linking ring entries could be worked on without having to type linking rings all the time. Budget = 20 USD
