I am using mongo db 3.2.8 on mac os. Here is a bug I'm facing when using language="none". My desired result was that when setting language="none", mongo DB will stop ignoring stopwords.

I have created a collection 'resources' with text index on a field called 'title' with default language (English.)

First, I create a document with title = 'What are you?'.

1. When I search with db.getCollection('resources').find({$text:{$search: 'what are you?'}}) I get no results as expected because all the words are stopwords.
2. When I search with
   db.getCollection('resources').find({$text:{$search: 'what are you?'}}, $language:"none"), I still get no results. Ideally, I'd like this to return the document.

Now I modified the document to have title = 'Whats are you?' (notice the typo 'Whats')

1. When I search with
   db.getCollection('resources').find({$text:{$search: 'whats are you?'}}, $language:"none"), I do not get this document even though there is an exact match and 'whats' is presumably not a stopword!
2. When I search with
   db.getCollection('resources').find({$text:{$search: 'what are you?'}}, $language:"none"), I get this document in return!
3. Language="en" is working fine: when I search with db.getCollection('resources').find({$text:{$search: 'whats are you?'}}) I get the result and when searching with db.getCollection('resources').find({$text:{$search: 'what are you?'}}), I don't.
