Ember data query from bottom-up approach?

I have a following data model:

University

.Colleges

..Departments

...Instructors

....Reviews

....Trainings

How can I get all reviews in a given college?

var rquery = store.query('review', {faculty.department.college._id : college._id})

or

var rquery = store.query('review', {faculty.department.college : college})

gives me a syntax error.

SyntaxError: quality-online/components/quality-chart.js: Unexpected token (50:44)

What is the best practice in this case, and how should I implement it?

Alternatively I could go with top down approach, and query all departments, instructors and so on with some nested for loop structure but would like to go other way if possible.
