I want to search and get only those tweets which has some conversations going on. Is there a way to do this? For instance if I search for the term “Entrepreneurship”, I want to find those tweets which has some people talking on it. I do not want to find tweets which do not have any replies from any one. Is this possible? If so, how can I do that?
This is not really possible, no. When you use the DataSift Live Streaming API, you will receive Tweets in real-time, so by the time you receive a Tweet, it is not possible that there will have been any replies to that Tweet.
If you have a collection of Tweets, you can set up a filter looking for Tweets responding to those Tweets using the twitter.in_reply_to_status_id target.
