• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cao) OR (vu cao)) ky nang mai hoi. hieu ve cham tuc va thanh vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cao) or (vu cao)) ky nang mai hoi. hieu ve cham tuc va thanh vi ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: ((tu cao) or (vu cao)) ky nang mai hoi. hieu ve cham tuc va thanh vi ((cua tre) OR (cua triet))*.
