      description: Returns a batch of scholarly works attributed to McMaster researchers. Observed 96 records per response against an `itemCount` of 273828 on 2026-09-01. The `aggregations` key is present on every response and was `null` in every response observed; the parameter that populates it was not discovered. `group` was probed and is NOT honoured — it is dropped from the echoed `params` and `itemCount` is unchanged.
      parameters:
      - name: q
        in: query
        description: Free-text filter. Observed narrowing `itemCount` to 11399 for `cancer`.
