### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU eRequesting CapabilityStatements for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described here and the syntax used to describe AU eRequesting interactions is defined here.

Any search parameter defined in FHIR may be 'allowed' by the system unless explicitly marked as "SHALL NOT".

12. `status` search parameter
    - including support for these `_include` parameters: `Task:focus`, `Task:owner`, `Task:patient`, and `Task:requester`

    `GET [base]/Task?status={system|}{value}`

    Example:

    1. GET [base]/Task?status=completed
    2. GET [base]/Task?status=completed&_include=Task:patient&_include=Task:requester&_include=Task:owner&_include=Task:focus

    Implementation Notes: Fetches a bundle containing Task resources matching the status (how to search by token)
