• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ly) OR (((sach doi) OR (sach hoi)))) lang ha hoi. hieu va cam tuc ban thanh di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ly) or (((sach doi) OR (sach hoi)))) lang ha hoi. hieu va cam tuc ban thanh di cua te~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ly) or (((sach doi) OR (sach hoi)))) lang ha hoi. hieu va cam tuc ban thanh di cua te*.
