             Summary: Expand filtering options for TwitterInputDStream
                 Key: BAHIR-117
                 URL: https://issues.apache.org/jira/browse/BAHIR-117
             Project: Bahir
          Issue Type: Improvement
          Components: Spark Streaming Connectors
            Reporter: Clemens Wolff
            Priority: Minor


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.
