• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cua me gioi cam hong minh ) OR ( tu sach ((tac kem) OR (tac ke)) giai han khang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cua me gioi cam hong minh ) or ( tu sach ((tac kem) OR (tac ke)) giai han khang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach cua me gioi cam hong minh ) or ( tu sach ((tac kem) OR (tac ke)) giai han khang minh ))*.
