Not able to search #code tweets


#1

Hi,

I am using the API v1.1 to get the Twitter feeds for the #tag. I am using the following code to get feeds. This code is not returning tweets for https://twitter.com/search?q=%23joes2pros. What is wrong with this code? Plz help.

//search= #Joes2Pros
public string GetSearch(string search, int count)
        {
            string resourceUrl =
                string.Format("http://api.twitter.com/1.1/search/tweets.json");
