ElasticSearch Stemming

I am using ElasticSerach and I want to set up basic English output. Thus, basically, fighters return a fight or any word that contains the root of the fight.

I am a little confused how to implement this. I read analyzers, tokenizers and filters, and there are several algorithms that can be used in ElasticSearch. I just don’t know which combination to use - snowball, stem, porter stems or synonyms.

In addition, a display example would be really useful.
