Nested FHIR Bundles -

can have fhir bundle( list of resources) within fhir bundle( list of fhir bundles) ? i'm building search api response should include list of resources , if resources have multiple related resources, should grouped in response fhir client can display without making additional api calls

yes bundle can contain bundles. note, though, include resources in bundle directly, since they'll resolved url. nesting bundles makes harder client. (see how _include defined in spec @ http://hl7.org/fhir/search.html#include)
