How to send logs to elasticsearch using logstash?

Question

elasticsearch

Hello! I installed the ELK stack, a file with Russian text was uploaded to the server. This file needs to be searched for specific words or meanings. As far as I understand, elasticsearch is engaged in search, kibana gives a convenient interface for viewing search results, logstash is needed in order to import logs (text) into elasticsearch. Actually the question itself is how to calculate how many times the word "Saltan" occurs and where in the Tale of Tsar Saltan?
