Token search: case sensitive or insensitive?


#1

Hi there,

I was reading the token search section and got confused with the following two sentences.

A token type is a parameter that provides an exact match search, either on a string of characters, potentially scoped by a URI.

By exact match search, I am assuming it meant it’s case sensitive. But then the sentence afterwards says:

For tokens, matches are literal (e.g. not based on subsumption or other code system features), but not case sensitive.

Is this saying that the “system” portion is case sensitive but the “code” portion is case insensitive? I am not sure what “tokens” the spec is referring to.

Thanks!

This has already been identified as an issue with the spec. A change will be made based on this gForge tracker item: https://gforge.hl7.org/gf/project/fhir/tracker/?action=TrackerItemEdit&tracker_item_id=13655&start=0
