Body: `"success":true`, `"result":{"count":27417, "results":[...]}`, and `len(results) == 1000` — exactly the standard CKAN/Solr `rows` ceiling, silent (HTTP 200, no warning field), with `count` still reporting the full 27,417-match total for the broad query `q=a`. ### `fl` (Solr field-list) trims the payload ``` curl "https://data.humdata.org/api/3/action/package_search?q=covid&rows=1000&fl=id,name" ``` → each result object is just `{"id": "...", "name": "..."}` instead of the full ~40-field dataset record (organisation, resources array, HDX-specific fields like `has_geodata`, `dataset_date`, `data_update_frequency`). For a client that only needs IDs to page through with `package_show`, `fl` turns a multi-hundred-KB response into a response small enough to request 1000 rows at once safely. A plain `rows=5000`/`rows=1500` request with the **full** field set (no `fl`) exceeded a 20 MB response-size guard in this lane before the clamp could even be observed at that size — reinforcing that the full per-dataset record (including every resource's metadata) is heavy; `fl` is the practical way to request a large `rows` page from this deployment. Full dataset records (via `fl`-unrestricted `package_search` or `package_show`) include `resources[]` with direct download `url`s on external hosts (Azure Blob, ArcGIS FeatureServer, etc.) rather than data proxied through HDX itself — HDX is a catalog over externally-hosted files, not a data-serving API for the files' contents.
