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