How to have clicking the phone's search button do nothing?

I'm trying to set up a screen so that when you click on the mag开发者_如何转开发nifying glass at the bottom of the phone it doesn't show the standard search area at the top of the screen: essentially, have it ignore (or catch it so I can do nothing) when the magnifying class is clicked on?

Override the onSearchRequested method of Activity class:

public boolean onSearchRequested() {

        // Do whatever you want here.


        return true;
}
