• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty ((hang ma) OR (tang ma)) hoi. hieu va ((cham xuc) OR (cham soc)) va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty ((hang ma) OR (tang ma)) hoi. hieu va ((cham xuc) or (cham soc)) va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ty ((hang ma) OR (tang ma)) hoi. hieu va ((cham xuc) or (cham soc)) va danh vi cua te*.
