Locate a nordnet identifier from symbol name

I have some issues with creating a reliable mechanism for getting nordnet identifiers from Symbol names.

I'm currently using the free text search GET /next/2/instruments with a query like:

query=CARL A&type=A&country=[DK]&limit=1&fuzzy=false

which gives me Carlsberg A as suspected but if i search on a dummy symbol e.g.

query=CARL Z&type=A&country=[DK]&limit=1&fuzzy=false

I still get Carlsberg A and not 204 or empty list.

Is there a reliable way to search the symbols and not the name text?

Regards
Jan
