ItemManager 2.0

[ChronosMe1]

Hello! Thanks for this great plugin!
I have one question.
I make a request with the conditions. If conditions only 2 or less ($imanager->getItems("slug=$slug", "active=1 && condition1=$condition1")) - all ok. But if I add conditions - ($imanager->getItems("slug=$slug", "active=1 && condition1=$condition1 && condition2=$condition2")) - It gives false or no results.
Whether it is possible to do more than 2 terms?

P.S. I am sorry for my poor English
