Answer 1

By default, MongoDB uses English for text index and the stop words are not indexed.

If you specify a language value of "none", then the text search uses simple tokenization with no list of stop words and no stemming.

So you should create your index like this :

db.my_collection.createIndex( { search_string : "text" }, { default_language: "none" } )
