• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((lang van) OR (dang van)) hoi. thien van nam thuoc ((va hang) OR (da nang)) di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu ((lang van) OR (dang van)) hoi. thien van nam thuoc ((va hang) or (da nang)) di cua te".
• Adding a wildcard symbol may retrieve word variants: te sach thu ((lang van) OR (dang van)) hoi. thien van nam thuoc ((va hang) or (da nang)) di cua te*.
