I mean response is same whether I go for General search or News search.
Just search for any keyword for General search and News search. You will get the same results.
Go through these get requests and see the differences, if any. (No difference)
General search : https://infinite-scrubland-15160.herokuapp.com/api/v1/search/bing?query=google&qtype=general&format=json
News search : https://infinite-scrubland-15160.herokuapp.com/api/v1/search/bing?query=google&qtype=news&format=json
