• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. ((nhieu viec) OR (((sieu viet) OR (su viet)))) cac truc va hang di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. ((nhieu viec) or (((sieu viet) OR (su viet)))) cac truc va hang di cua te".
