• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ha ve gioi con hoang minh ) OR ( ((su sach) OR (vu sach)) ha te doi song thuong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ha ve gioi con hoang minh ) or ( ((su sach) OR (vu sach)) ha te doi song thuong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( thu sach ha ve gioi con hoang minh ) or ( ((su sach) OR (vu sach)) ha te doi song thuong tin ))*.
