I second what Jukka suggested, once you move to Postgis as the index you can expose it via WFS and do quite complex filtering/queryin on top of it.
E.g. you can get the last available time via a WFS query in a variety of ways using WFS ordering + limiting results' number + filtering. Regards, Simone Giannecchini == Our support, Your Success!
