• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) v nang ma hoi. ((hieu ve) OR (lieu va)) cau tuc xa thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) v nang ma hoi. ((hieu ve) or (lieu va)) cau tuc xa thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) v nang ma hoi. ((hieu ve) or (lieu va)) cau tuc xa thanh vi cua te*.
