Quick intro

The _count search parameter returns the number of requested resources per page (excluding the resources returned with _include search parameter) as requested by the client.

_count search parameter

The use of Paging to manage response times relating to the volume of data returned is done by the PCA™ server.

If the _count selected by the client is larger than the total per page size set by the PCA™ server, the PCA™ server setting will apply. 

In the example below, the client has a set _count to 10. This represents the total number of matches, not how many resources are returned in a particular response.

The link attribute allows the subscriber system to traverse the bundle through the use of paging.
