• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ly ((nang xa) OR (nang x)) hoi. hieu vu cham xuc va ((han thai) OR (ban thai)) va thieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ly ((nang xa) OR (nang x)) hoi. hieu vu cham xuc va ((han thai) or (ban thai)) va thieu".
