I am trying to extract bond information in java using the restapi. I can extract some fields like in this method: searchbyisinrequest.png
But I need more fields like "Frequency Code Description" or "Day Count Description", as in the following template:template.png
When I include i.e. .put("Frequency Code Description") in the method, the error is 400 (Bad request). So I don't know why I can extract some fields, but no others and what can I do to obtain day count, frequency,...
