/suggest/items and /suggest/properties are the REST API equivalents of wbsearchentities in the Action API. wbsearchentities has a maximum page size (limit) of 50 results for basic users, and 500 for users with the apihighlimits right. For /suggest, the maximum limit is 500 for all users.
This difference seems strange from the user perspective and also makes the underlying code unnecessarily complicated. We should consider applying the same limits to both.
AC:
- Limits are consistent with what is currently being done in the Action API
