Single Search Field for GridView


I’m looking to see if anyone has been able to come up with a way to use a single search field that covers multiple columns (fields) in a GridView. What I’m trying to get to is Google’s single search field type of interface that people know and know very well.

Also is there a way to place that field anywhere I want? Normally when you set up a search model and use it with a GridView each column has the search field above it. I’d rather have the search field be somewhere else. Can I do that?

Sorry to be so vague.
