Hi all,  
I wonder if anyone knows how to solve this one: I'm trying to mimic Linux  
"grep" command behavior in Elastic Search.

_The problem:_  
Sending search request for "hello world" should first return all matches  
where these two words come together in a sentence. However, internal  
Elastic Search ranking kicks off instead, returning matches with high  
appearances of "hello" or "world" words.

_Current configuration:_  
I'm indexing file contents using the attachments plug in from  
[https://github.com/elasticsearch/elasticsearch-mapper-attachments](https://github.com/elasticsearch/elasticsearch-mapper-attachments) (mappings  
attached).  
I was suspecting analyzer breaking the original file structure, so I tried  
to disable it by using { "index": "not analyzed" }, but it didn't help.

Appreciate any advice you can come up with 🙂

Thanks,  
Sergey.
