Earlier in this function, L846, you use overlay()->contents(), which is the same
thing.  Define this up there and just use it throughout.

ASSERT_GT .. doesn't make to continue if this fails.

What it you just look up "!!sorted[0].is_search" and check that it is false? 
That should cover both the false and undefined cases.
