It's not the most "full featured" search function - if zoom factor is less than '40' it will zoom to that level, otherwise it will preserve any higher 'power' of zoom. It might occasionally take you somewhere unexpected, as disambiguation isn't supported (yet).
You can also trigger a search from the querystring, so you can 'bookmark' a search, like this:
silverlightearth.com/2b2/?q=Golden Gate Bridge
or with zoom specified as well (note it's "DeepZoom Zoom Factor" and not your usual VE 1..18 range)
silverlightearth.com/2b2/?q=Seattle Space Needle&z=8000
"Reset" zooms back to the starting viewpoint. It seems I've broken the overlay with these changes - fix to come...
OT: this is one case where it's actually easier not to use DeepZoom - check out how much faster the Silverlight 1.0 version loads
silverlightearth.com/?q=Seattle Space Needle&z=16
UPDATE (25-Jun): Accepts both "Zoom Factor" AND "Tile Level"... if z < 18, z^2 is used as the "Zoom Factor", eg.
Map selection is also supported from the URL, for example
The map 'codes' are backward compatible with Silverlight Earth 1.0.
