• If you are trying to use Boolean operators, they must be ALL CAPS: hoc anh ((ky sang) OR (ky dang)) ((tao hoi) OR (tao boi)). hieu ve pham duc va tinh lap cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc anh ((ky sang) or (ky dang)) ((tao hoi) OR (tao boi)). hieu ve pham duc va tinh lap cua te".
