• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((hang xa) OR (hang ca)) hoi. hieu va ((cham cuu) OR (chat cua)) ban thanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((hang xa) or (hang ca)) hoi. hieu va ((cham cuu) OR (chat cua)) ban thanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: te sach y ((hang xa) or (hang ca)) hoi. hieu va ((cham cuu) OR (chat cua)) ban thanh dai cua te*.
