Filtring tweets with logstash filter plugin

Elastic Stack Logstash
1

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) 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

I think my Regular Expression is false

Perhaps \bgiveaway\b would be enough?

I got an error msg

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

Yes, excuse my mistake.
\bgiveaway\b doesnt work .
