?search not working on json : I am new to json and APIs. 

This particular dataset I am working with (https://api.cdnjs.com/libraries) is searchable by placing "?search=search_term" behind it (like: https://api.cdnjs.com/libraries?search=cloud). But when I use another json dataset (http://api.nobelprize.org/v1/prize.json for instance) it gives an error ({"error":"Using an unknown parameter"}). Does this have to do with how the datasets are set up? Methods perhaps? How do I make the other json searchable like that (so I can use it in my search app)
