If using the generic CBVs you can override .get_queryset() to implement filtering just as you would with regular Django CBVs.

There's also an outstanding pull req to build in support for django-filter and other filtering backends which now just needs some docs, and which I plan to have merged in within the next few days or so. https://github.com/tomchristie/django-rest-framework/pull/29... That'll make it easier to do more complex filtering stuff. (And eventually have the filters be presented in the Browsable API)
