asking for multiple fragments from the same resource

I have this resource... 
 

 example.com/my/api/32
 

 It returns 'n' pieces of data. I want to return only one "data_q"...
 

 example.com/my/api/32#data_q
 

 easy enough. But what, in your view, should done if I want 3 pieces of data?
 

 I really don't think this is kosher...
 example.com/my/api/32#data_a#data_q#data_z
 I really do't think asking for multiple fragments constitutes a query...
 example.com/my/api/32?data=data_a,data_q,data_z
 

 I would love to hear your ideas.
 

 Thank you
