• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky dang van hoi. hieu ((van lam) OR (van nam)) duoc ((le thanh) OR (va tinh)) hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky dang van hoi. hieu ((van lam) OR (van nam)) duoc ((le thanh) or (va tinh)) hai cua tre".
