AJAX in SharePoint 2003 : Nifty Search AJAX Code

Carlos Segura Sanz has published some very cool AJAX code to run SharePoint searches and return results without a screen refresh… now what I would like to do is adapt Matthew McDermott’s SharePoint People Finder code to run with the AJAX of Carlos…

The thing is the AJAX code by Carlos runs direct queries against the DB (I believe) whereas the People Finder passes custom search parameters to the existing search.aspx page.

Any ideas or comments most appreciated.
