This operation allows a client to find an identified list for a particular function by its function. The operation takes two parameters, the identity of a patient, and the name of a functional list. The list of defined functional lists can be found at Current Resource Lists. Applications are not required to support all the lists, and may define additional lists of their own. If the system is able to locate a list that serves the identified purpose, it returns it as the body of the response with a 200 OK status. If the resource cannot be located, the server returns a 404 not found (optionally with an OperationOutcome resource).

The canonical URL for this operation definition is


Formal Definition (as a OperationDefinition).

URL: [base]/List/$find

This is an idempotent operation

In Parameters:

The id of a patient resource located on the server on which this operation is executed


The code for the functional list that is being found

Note that servers may support searching by a functional list, and not support this operation that allows clients to find the list directly
