I want to test the index/\_source compression of elastic search.  
But I think it is not working perfectly.  
Someone knows about the compression?

1. 

- tokenizer : standard

- index compression : true

- size of index : 2.78G

- tokenizer : standard

- index compression : false(default)

- size of index : 3.00G

1. 

- tokenizer : standard

- source compression : true(default)

- size of index : 3.17G

- tokenizer : standard

- source compression : false

- size of index : 3.01G

1. 

- tokenizer : n-gram(2-5level)

- index compression : true

- size of index : 8.01G

- tokenizer : n-gram(2-5level)

- index compression : false(default)

- size of index : 7.99G

please help me...
