• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu khach)) y nang o hoi. hieu ve cam xuc gia ((thanh lam) OR (thanh nam)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) y nang o hoi. hieu ve cam xuc gia ((thanh lam) OR (thanh nam)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu khach)) y nang o hoi. hieu ve cam xuc gia ((thanh lam) OR (thanh nam)) cua triet*".
