Hi Mohamed. We have a basic getting started topic for setting up Filebeat to work with the Elastic stack:
https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-getting-started.html. (Note that the instructions for setting up the stack itself are here: http://www.elastic.co/guide/en/beats/libbeat/1.0.1/getting-started.html.)
For information about filtering, you'll need to look in the Logstash Reference: https://www.elastic.co/guide/en/logstash/current/index.html
Note that the search functionality on the documentation page has very recently been enhanced. You can now constrain your search to specific documents (in addition to searching across the documentation set).
But it sounds like you might be looking for a more comprehensive tutorial that walks you through the setup for your specific use case. We have nothing quite like that at moment, but I'm really interested in hearing why you find it hard to work from the documentation.
Is your comment specific to the Elastic documentation, or do you just generally prefer working with tutorials?
If you are having trouble with the Elastic documentation, I'm really interested in hearing where you are encountering problems. Are you having trouble locating specific information? When you find the information, does it make sense? Is there simply not enough information for your specific use case?
Any specifics that you can provide will really help us improve the documentation.
