• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (thu san)) ky nang ha hoi. hieu van lam duoc van thinh vi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) OR (thu san)) ky nang ha hoi. hieu van lam duoc van thinh vi ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: ((tu san) OR (thu san)) ky nang ha hoi. hieu van lam duoc van thinh vi ((cua tre) or (cua te))*.
