so this one is behaviorally different from the rest.  Although I'm not 100%
convinced it's the right thing to do, but it seems like the default behavior for
search should move from this file to ContentViewCore to keep it consistent. 
None of the other actions have default behaviors defined as they all call out to
the action handler and don't attempt to do anything with the response.

So, we'd either need to clarify all the apis to signify this one is different,
or we should move it to one consistent place.

I updated this to work as you'd expect.  I removed all boolean return values
(never used?) and pulled all specific logic out to the ActionHandler
(ContentViewCore).  I don't like putting the logic there but that makes more
sense than where it currently is.
