Querying in logstash

My task is to configure logstash to receive twitter posts that are related to a certain event. Based on that I need to be able to search for terms specified. From what I've read so far, I need the whole ELK stack to query the terms.

I think I can configure it based on this configuration http://david.pilato.fr/blog/2015/06/01/indexing-twitter-with-logstash-and-elasticsearch/.

But again, I can receive a tons of tweets in the log file but cannot query them properly. Any ideas please??

You need to explain what you mean by properly, cause that's a little vague :slight_smile:
