Does twitter.mentions filter (http://dev.datasift.com/docs/targets/twitter/twitter-mentions) includes all mentions and replies that an id gets? Since reply is sort of like a mention with additional fields set like in_reply_to_user_id and in_reply_to_tweet_id. Or do we need to use both twitter.mentions and twitter. in_reply_to_screen_name in order to filter for all mentions and replies for a user X?
Twitter.mentions will include any @username mentions including replies. So the following filter:
twitter.mentions in "DataSift"
will include anyone mentioning @DataSift, replying to Tweets from @DataSift, or writing their own "RT @DataSift ..." retweets.
Thanks for the confirmation Jason.
