Hi, i'm working on a ELK project to extract data from twitter to elasticsearch and build a sentimental analyses engin.  
I need to know how can I filter spammed tweets with logstash ? Is that possible or not ?  
for example, if i want to ignore all tweets that contain the word 'freebitcoin' or 'bitcoin giveaway', how can i do it?  
Thank you.

Have a look at conditionals ([https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html](https://www.elastic.co/guide/en/logstash/current/event-dependent-configuration.html)) and the drop filter.

That's what i did, but when i visualized my data with kibana, i still found tweets that contain the keyword 'giveaway' ![c4](https://us1.discourse-cdn.com/elastic/original/3X/f/0/f0d084cceee2f7a8e0216d595263e01f92f27b72.PNG)

Perhaps `\bgiveaway\b` would be enough?

Well, you obviously need the surrounding slashes. My example was only the expression itself.
