Search questionnaire responses

The logical id of the resource to search for. Matched exactly and case-sensitively; it does not accept the system|value form. A resource belonging to another clinic returns no match rather than an error.

Filter by last-updated time. Accepts the prefixes ge, gt, le and lt, or no prefix at all, which matches the whole period given. A bare date such as 2026-08-01 therefore covers that entire day.

Number of results per page. Defaults to 50 and is capped at 100: a larger value returns 100 rather than an error.

Comma-separated list of fields to sort by (prefix with '-' for descending).
