Some filters work in, but do not work in API (twurl)


I want to use from:user filter in a query. I put this query “polar bear from:9NewsGoldCoast” in the search box in, and it returns some results. But when I execute it with twurl using the command:

$twurl “/1.1/search/tweets.json?q=polar bear from:9NewsGoldCoast”

it doesn’t give me any result. What could be the problem?
