Error Code 215: twitter search api?

Question

I am using the twitter search API 1.1 and getting this response

 {"errors":[{"message":"Bad Authentication data","code":215}]}

The query I am constructing for search is

https://api.twitter.com/1.1/search/tweets.json?q=.priyanka%20chopra

Am I making the right query or not? Please help me out

The query seems OK, but, are you authenticating your request via OAuth?
