How to use Patient age search extension

1

Hi, I found below search option for patient age but it is not working in Hapi Fhir server. May I know, how to use it ?

https://www.hl7.org/fhir/patient-profiles.html#search

8.1.17.3 Search Extensions

|age|number|Searches for patients based on age as calculated based on current date and date of birth. Deceased patients are excluded from the search.

Does the HAPI server declare support for the search parameter?
