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