• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky ((sang lai) OR (mang lai)) hoi. hieu ((van chat) OR (cao chat)) lua va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky ((sang lai) or (mang lai)) hoi. hieu ((van chat) OR (cao chat)) lua va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu dan ky ((sang lai) or (mang lai)) hoi. hieu ((van chat) OR (cao chat)) lua va danh vi cua te*.
