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