• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ly nang ((x hoi) OR (x ho)). hieu ve cham ((xuc va) OR (luc va)) hanh vai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ly nang ((x hoi) OR (x ho)). hieu ve cham ((xuc va) or (luc va)) hanh vai cua viet*".
