Ember query api with multiple parameters

I was wondering if it was possible to query the API with multiple parameters in one go.

I know we can do

this.store.find("assetType",{category:"ancillary"});

which will do a query of http://ift.tt/1Bsd8n3

But what I want to do is a query of http://ift.tt/17X0oai

Is this possible to do this in Ember on one go. Or will I have to do a filter on the results of the first query instead?
