Last updated 21 days ago
Overview
The ValueSet resource official FHIR documentation can be found here: https://www.hl7.org/fhir/valueset.html.
All examples below can be executed in the REST Console of your Box in Aidbox.Cloud. Just copy/paste a sample into the REST Console and click the EXECUTE button or press Ctrl+Enter.
Also, you can run all examples in Postman having Aibox.Dev running locally, or by setting up a box in Aidbox.Cloud. Download the Aidbox collection and open it in Postman. Setup the proper environment value for the base variable which should be the base URL of your FHIR server. Setup authorization if you are using Aidbox.Cloud.

Regular Expression
Aidbox supports filter opearion regex and implements Postgresql regular expressions.  See the documentation here: https://www.postgresql.org/docs/9.3/static/functions-matching.html#FUNCTIONS-SIMILARTO-REGEXP.
Please notice that regular expressions require additional character escaping in JSON.
Let's include codes where the specified property of the code matches the regex specified in the provided value \\w{8}. The result will include 4 values which length is 8 symbols: proposed, accepted, achieved, and rejected.

This parameter is not supported in Aidbox.
Exists
The specified property of the code has at least one value (if the specified value is true; if the specified value is false, then matches when the specified property of the code has no values).
Let's display concepts where property hierarchy exists. The result will include 8 concepts for which hierarchy is not an empty array: achieved, ahead-of-target, behind-target, in-progress, on-hold, on-target, planned, and sustaining.
