• If you are trying to use Boolean operators, they must be ALL CAPS: hoc nganh ((ky lang) OR (ky dang)) van hoi. hieu ve cac duc va ((hanh thai) OR (nhanh thai)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc nganh ((ky lang) or (ky dang)) van hoi. hieu ve cac duc va ((hanh thai) OR (nhanh thai)) cua te".
• Adding a wildcard symbol may retrieve word variants: hoc nganh ((ky lang) or (ky dang)) van hoi. hieu ve cac duc va ((hanh thai) OR (nhanh thai)) cua te*.
