// (1) A search request with a single result comes back with that single result as json.
// (2) A search request with multiple results comes back with those results as an array in the
// verification_requests property.
// (3) A search request which comes back in error has different Status values than search requests
// that come back without error. (See VerifyStatus vs VerifyDetails.Status)
// If the results has a verification_requests node then we can successfully map our object as normal.
