Short answer: no – the IRIS for Health FHIR server doesn’t expose an _offset / _skip (or similar) parameter for random-access paging. We do support

• Standard FHIR paging via Bundle.link[next] / Bundle.link[prev]
• Control over page size and max total results, but not “jump to page N”   If you need “jump to arbitrary position” or more sophisticated pagination in an app, your options are basically:
• Stick with FHIR paging
  • Use _count to set a page size that’s convenient.
  • Follow next links and optionally prefetch ahead a page or two in your client so the UI feels snappy when users jump forward.
• Page over SQL instead of FHIR
  • Load/search your data via Resource Repository / FHIR SQL Builder and then query it with SQL, where you do have OFFSET/FETCH or equivalent.
  • Your UI can then use traditional page numbers while the FHIR server is just the ingestion layer.

@Evgeny Shvarov the port to use is the port to communicate with the FHIR repository on IRIS for Health. For the community edition with the webgateway running on IRIS for Health, the port is 52773. When I use no PWS and the Webgateway the port is the webgateway port which frequently is port 80.
