How to search in files for a string using ElasticSearch search engine?

How to search in files for a string using ElasticSearch, OpenSemanticSearch(http://ift.tt/1kJ0BS8) and laravel 5.1?

I want to index all the data in all files, then can search it using these above tools.

I have researched a lot but didn't find full tutorial or example.

So please help.
