Using the Valence REST API, how to search for course(s) by name or by semester name

Paul.F.779

I am new to this. I authorize using oAuth2 (PHP and cURL) and can query or update our D2L Brightspace data from our Student Information System. But is there an API function for :

1.Searching for a course(s) by name, ex. "Science"? I can only list ALL of courses.

2.Searching for a course(s) by semester name? 

Currently, I can only list ALL courses. I can't seem to find search function.

using route:

  https://abcd.onlinelearningbc.com/d2l/api/lp/1.35/orgstructure/
with parameter 'orgUnitType' of '3' which are Course Offerings.

This returns JSON of all courses, but I would like to be able to narrow the search.
