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