• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (su sach)) ((thu nang) OR (thu hang)) o hoi. hieu va cam cuc ban danh d cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (su sach)) ((thu nang) OR (thu hang)) o hoi. hieu va cam cuc ban danh d cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (su sach)) ((thu nang) OR (thu hang)) o hoi. hieu va cam cuc ban danh d cua tre*.
