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