Hi  
In our project we often dealing with logic like "full document field should be present in the lookup query".  
We've developed number of solutions for this (usage of highlighter, generation of tons of queries with all lookup term combinations, etc). But all this approaches are too slow.  
Maybe there is a faster and simpler way to implement these logic?  
For example you have document  
`{"text": "hello world"}`  
It should be found by query  
`hello world my friend`  
But not found by query  
`hello my friend`

Seems like you could use a [terms set query](https://www.elastic.co/guide/en/elasticsearch/reference/master/query-dsl-terms-set-query.html) here, where `required_matches` is the number of tokens in each doc's `text` field.
