Search for identifier text


I am trying to search for a patient using a portion of the identifier display, for example suppose that there is a patient with the identifier { “system”: “urn:CPF”, “code”: “12345678901”, “display”: “12345678901” } and we made this request for the API

The problem with this way is that the search will look for all systems but I want search only for urn:CPF

So how could I make the search using system and display?

You’d have to define a custom SearchParameter - and get all relevant systems to support it. (Also, I’m not clear that urn:CPF is a valid URN?)
