This article is a technical blog summarizing a search tutorial presented at FHIR DevDays. It provides access to a Postman collection containing 50 Patient Bundles, enabling the execution of various queries. The 19 featured queries range from simple ID lookups (Query 1) to complex data retrieval methods, including filtering by specific time periods (Query 7, 13), utilizing reference relationships for data joining (_include, _revinclude) (Query 10, 12, 11), and advanced filtering using SNOMED CT or HL7 code systems (Query 9, 18). Specifically, the use of `date:ge`/`date:lt` for date range specification and complex path searches like `_has:Observation:patient:value-concept` offer deep technical insights into extracting necessary information from real clinical data. Furthermore, the guide details how to define custom SearchParameters, allowing flexible query construction based on specific business logic. These concrete steps and code examples are highly valuable for developers utilizing FHIR APIs, offering practical models for improving interoperability in healthcare IT systems globally.
