• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((mang xa) OR (nang x)) hoi. ((hieu va) OR (hieu qua)) cao xuc va thanh dieu cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((mang xa) or (nang x)) hoi. ((hieu va) OR (hieu qua)) cao xuc va thanh dieu cua tre*".
