• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang x hoi. ((hieu ve) OR (hieu va)) cac xuc ((cam dan) OR (nam dan)) vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang x hoi. ((hieu ve) or (hieu va)) cac xuc ((cam dan) OR (nam dan)) vai cua te*".
