• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty xang ((tao hoi) OR (tao khoi)). hieu ve cham luc va thanh hai ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty xang ((tao hoi) OR (tao khoi)). hieu ve cham luc va thanh hai ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: tu sach ty xang ((tao hoi) OR (tao khoi)). hieu ve cham luc va thanh hai ((cua tre) or (cua te))*.
