Introduction to FHIRPath
summary
FHIRPath is a concise tree-walking language used for extraction, validation and search indexing; examples show navigation like patient.name.given, filtering with where(system='email'), and predicates such as valueQuantity.exists. Demo uses the online FHIRPath evaluator and Brian Pose’s FHIRPath tester, then posts a custom SearchParameter (201 Created) that targets an extension URL, updates a patient to trigger reindexing, and successfully returns the patient when searched by birthplace, with the new index row visible in the server tables.
