• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((v nang) OR (va nang)) xa hoi. hieu qua cac xuc van anh ((viet cua) OR (viet qua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v nang) OR (va nang)) xa hoi. hieu qua cac xuc van anh ((viet cua) or (viet qua)) triet".
