How to create doesNotContain query using incasesensitive behavior using java mongo driver

[Yogesh Yadav]

Hi, 

I am pretty new to MongoDb. However I wanted to create following queries with incasesensitive behavior using java mongo driver 

1) 'doesNotContain' query:

Similar to following mongo query Ex: db.mydb.find({"myfield" :{$not:  /myvalue/i}})

This query should return records where 'myfield' does not contains 'myvalue'

2) Exact match or equal query:

Ex: db.mydb.find({"myfield" :"myvalue"})

This query should return records where 'myfield' completely matched with 'myvalue' but with incasesensitive behavior

Please suggest 

Thanks,
