• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky dang ha hoi. hieu ((van lam) OR (((van cau) OR (van hau)))) loc va dan va cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang ha hoi. hieu ((van lam) or (((van cau) OR (van hau)))) loc va dan va cuu tre*".
