• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu mach cua mes gioi bon cong tan ) OR ( su sach cha ((me giai) OR (ke giai)) hon tdong tinh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu mach cua mes gioi bon cong tan ) or ( su sach cha ((me giai) OR (ke giai)) hon tdong tinh ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu mach cua mes gioi bon cong tan ) or ( su sach cha ((me giai) OR (ke giai)) hon tdong tinh ))*.
