A \"faceListId\" is created by [FaceList - Create](https://docs.microsoft.com/rest/api/faceapi/facelist/create) containing persistedFaceIds that will not expire. And a \"largeFaceListId\" is created by [LargeFaceList - Create](https://docs.microsoft.com/rest/api/faceapi/largefacelist/create) containing persistedFaceIds that will also not expire. Depending on the input the returned similar faces list contains faceIds or persistedFaceIds ranked by similarity.\n<br/>Find similar has two working modes, \"matchPerson\" and \"matchFace\". \"matchPerson\" is the default mode that it tries to find faces of the same person as possible by using internal same-person thresholds. It is useful to find a known person's other photos. Note that an empty list will be returned if no faces pass the internal thresholds. \"matchFace\" mode ignores same-person thresholds and returns ranked similar faces anyway, even the similarity is low. It can be used in the cases like searching celebrity-looking faces.\n<br/>The 'recognitionModel' associated with the query face's faceId should be the same as the 'recognitionModel' used by the target faceId array, face list or large face list.\n",

If follow-up operations like Verify, Identify, Find Similar are needed, please specify the recognition model with 'recognitionModel' parameter. The default value for 'recognitionModel' is 'recognition_01', if latest model needed, please explicitly specify the model you need in this parameter. Once specified, the detected faceIds will be associated with the specified recognition model.
