• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cach) OR (tu cach)) tu lang xa hoi. hieu van lam ((luc va) OR (tuc va)) nang va chua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cach) OR (tu cach)) tu lang xa hoi. hieu van lam ((luc va) or (tuc va)) nang va chua triet".
