{description: 'For input parameters that are codes, the simple FHIR [token](https://hl7.org/fhir/R4/search.html#token) search parameter type is used instead of the complex `Coding` datatype. This allows either the ''GET''  or the ''POST'' syntax to be used to initiate the interaction in many cases. The `Reference` datatype is used for resources references, which allows the requester to use either a reference to existing resource, or an identifier ([logical reference](https://hl7.org/fhir/R4/references-definitions.html#Reference.identifier)). Examples of both are shown below.  \n- If multiple patients are provided as parameters, this conveys the need for a group appointment. \n- If more than one non-patient participant type of parameter is present (e.g. a Provider and a Location), the response SHOULD contain appointments with *all* of these participants (i.e, this is a logical ''AND''). If a particular participant type is repeated, the response SHOULD contain appointments with *any* of these participants and SHOULD be interpreted as the order of preference (i.e. this is a logical  ''OR'' and  does not drive a joint appointment with multiple practitioners. locations or organizations). Ultimately the server is responsible for determining the first/best available appointment options to return.  \n- References can be to an absolute URL, but the Scheduling Server can create or modify resources only  on the resources on the server or a defined domain.  \n- To set the upper limit on the total number of available appointment options to return use the standard [`_count`](https://hl7.org/fhir/R4/search.html#count) search parameter.  See the examples below for how this is implemented. \n- The Scheduling Server SHALL NOT include any held appointments (i.e. appointments that were reserved as a result of a previous ```$hold``` operation, and for which the holding period had not expired) in the list of potential appointments.', package_name: servicewell.fhir.frenda-wof-connect-flc, name: FindAppointmentsOperationFrenda, type: 'true', package_version: 0.1.3, class: operation, kind: operation, url: 'https://canonical.fhir.link/servicewell/frenda-wof-connect-flc/OperationDefinition/FindAppointmentsOperationFrenda', version: 0.1.3}
