• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tru tang ma hoi. hieu ve cam thu ban thanh loi ((((cua tre) OR (cua te))) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tru tang ma hoi. hieu ve cam thu ban thanh loi ((((cua tre) OR (cua te))) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: su sach tru tang ma hoi. hieu ve cam thu ban thanh loi ((((cua tre) OR (cua te))) or (cuu tre))*.
