I have almost 60 milion+ data of user information in mongodb. I want to have a filter option in my website, so that user can come and filter data by location. So, in location search bar, if a user type any string then the location match with those string will be shown as suggestion.All I want a similar feature like linkedin.Don’t know how can I make this.

Please suggest me an way to build similar functionality so that suppose if I search florida, then the search suggestion appears with some of the location of florida
