• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (tu cong)) xa hoi. hieu qua cam ((xuc va) OR (luc va)) hang de cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) or (tu cong)) xa hoi. hieu qua cam ((xuc va) OR (luc va)) hang de cua te*".
