Filtered Search Results


I am making an application that should be able to get Tweets posted from a given location & radius or within a certain window of time,
and I am running into 2 issues.
Note: My app should NOT require a user-context.

The first problem is making time-based searches.
The location-based queries were very straight-forward, but I cannot figure out how to form temporal queries.
The only resources I have found on the topic are here:

The second problem is filtering results based on kind (i.e. text, image, video, etc.)
Is there a way to only receive results that contain an image?

Thanks for your time!
