hello Bryan,
i have done searh functions in my mobile apps (dataView control), and I did it like this.
1) Bind edit box to a Request variable:
2) in search property of a view, i have this code:
if (requestScope.searchTxt != null)
{ return requestScope.searchTxt + "*";}
3) Add button labeled "Search" of the submit type (to send request to the server)
It's simple way of doing it, and search works ok. Hope it helps!
