nit: The notion of "embedded search" is not very clear to me -- can you expand
this comment a bit to explain what the distinction is, or perhaps just mention
the expected use-case?

Agreed.  I've renamed to use the "Instant Extended API" terminology used
elsewhere.  It is a url alternate for use by the new Instant work.
