Is it possible to perform the following kind of streaming filter (pseudocode)?
(track = "shooter" and location = "Miami") or (track = "flood" and location="Los Angeles") or ...
I think it might not be possible because of the following (quoted from the documentation):
The track, follow, and locations fields should be considered to be combined with an OR operator.
No, this is not possible. You would need to use the enterprise PowerTrack API.
