Some few problems when dealing with API projeqtor

Hello,

I'm trying to deal with API projeqtor in order to :
1- Return list of ComponentVersion by idComponent :
mywebsite/api/ComponentVersion/search/idComponent=15 but it returns always empty list. ==> {"identifier":"id", "items":[] }
However, I have many Component in database with idComponent = 15
2- Return all TestCases under TestSession:
I can't find what URL I need to use.
I'm able to return all TestSession: mywebsite/api/TestSession/
I can get also all TestCase : mywebsite/api/TestCase/all
but I can't find any relation between test case and test session in data returned by URLs above

Any help please ?
