• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky sang xa hoi. hieu ve cham xuc ban thanh doi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ky sang xa hoi. hieu ve cham xuc ban thanh doi ((cua tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu san)) ky sang xa hoi. hieu ve cham xuc ban thanh doi ((cua tre) or (cua triet))*.
