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