• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ha ve gioi bon hong minh ) OR ( su sach cha me gioi bo ((cong vinh) OR (cong viec)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ha ve gioi bon hong minh ) or ( su sach cha me gioi bo ((cong vinh) OR (cong viec)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach ha ve gioi bon hong minh ) or ( su sach cha me gioi bo ((cong vinh) OR (cong viec)) ))*.
