Search in Progress

Hi, I am developing a simple site, in PHP4, which has three frames on it. The first gives you the search options and the second two, the results. What I was wondering was, while the database is being searched, is it possible to display some text in the 'results' frame stating that the search is in progress? I also have another site which I would like do this on, however this one, rather than using frames, uses tables, and it is only when the entire set of data for each table has been retrieved that the page is actually displayed. Any suggestions would be most appreciated Alexis
