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