• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac hoi) OR (sat hoi)) lang xa hoi. hieu va chat tuc ((va dinh) OR (va tinh)) va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac hoi) OR (sat hoi)) lang xa hoi. hieu va chat tuc ((va dinh) or (va tinh)) va cua tre*".
