Logstash doesn't capture Retweet?

I am trying to use Logstash to collect Twitter Steaming data. Every thing looks great, but one thing is missing I guess. It seems that Logstash is not injecting Retweets in ES. Any idea? btw, ignore_retweets is set to false. So, fields like


are missing altogether from the collected raw tweet.

See Twitter plugin retweeted is always false
