• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chiet) OR (((thep viet) OR (thai viet)))) tach - hanh ban cua nhung cong dan than tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chiet) or (((thep viet) OR (thai viet)))) tach - hanh ban cua nhung cong dan than tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chiet) or (((thep viet) OR (thai viet)))) tach - hanh ban cua nhung cong dan than tap*.
