Topic: How to do prefix search for token parameter?
shoho (Apr 26 2021 at 08:00):
There are two examples I want to search.
1.Patient resource having the following property.
"telecom": [{"system": "phone", "value": "0311112222"}]
I want to search the patient even with partial phone number (0311).
2.Patient resource having the following property.
"identifier": [{"type": {"text": “CIVIL ID”},"value": "1111111111"}]
I want to search the patient even with type and partial value (11111).
Thank you.

Token search is defined as "close to exact match". It is not expected to search partial values.
ContactPoint (for telecom) has a special case "At the discretion of the server, token searches on ContactPoint may use special handling, such as ignoring punctuation, performing partial searches etc." but this is implementation dependent.

If you want to do a contains search on phone number or identifier, you'll have to define a separate search parameter (of search type 'string') to do that.

(And convince the relevant servers to implement it.)
