Can AQL set filter by edge type not attribute of the edge?

[Walt Li]

I have a question about AQL 

In The City Graph, we can use the distance attribute to filter the desired city node. 

But if I want to query the city that can be reached directly from Berlin by germanHighway. I don't want the internationalHighway.

How to query? 

Need I to make a attribute for  Edge germanHighway called "travel-method":"germanHighway" and Filter by the "travel-method" attribute?

Hi,

if you don't use the named graph, but use the 'collection sets' query method, you can specify which edge collections of a graph to include:
