Face recognition - several results/set a threshold for similiartity?

is there a way to get multiple most simliar faces in return? Is there a way to set a threshold lest's say 0.75 similarity?
Is there a way to limit amount of returned similar faces?

Review the face-recognition API behavior described in the issue and determine how similarity results are currently returned. Clarify the expected behavior for multiple matches, a 0.75 similarity threshold, and a maximum result count. Done means the API supports and documents the agreed options with tests covering them.
