> Project: Bahir

> Currently, the TwitterInputDStream only supports filtering by keywords [1]
> which corresponds to the "track" option in the Twitter API [2]. The Twitter
> API supports many more ways to receive a filtered stream (e.g. get Tweets in
> a particular location [3]). It would be very useful to expose these
> additional filtering options in this library.
> Proposal: add a new public method to TwitterUtils which follows the same
> interface as createStream [4] but which takes a FilterQuery [5] object as
> argument. In this way, we give full filtering flexibility to our users.
> I'm currently working on Project Fortis, a social data analysis platform for
> the United Nations [6]. The extra filtering options would be very useful for
> my project so I'm happy to implement this and create a pull request.
