| Filter type | Behaviour |

| Date range | Format must be YYYY-MM-DD — anything else returns 400. |
Result limits
Search returns a maximum of 500 results with no pagination. If your query matches more than 500 entities, only the first 500 are returned — with no indication that results were truncated. Narrow your filters to stay under the limit. If you need the full register, use Local storage instead.Common patterns
