Search

Search for a resource on server, which will return a bundle with a list of resources. In Gleam, patient_search will return just a list of patient resources, whereas patient_search_bundled will return the entire bundle, which can have other resource types. Use search parameters to narrow searches, such as patient name. In Gleam, SpPatient contains the search params for a patient, and sp_patient_new creates an SpPatient with no params set.
