• Performing a fuzzy search may retrieve terms with similar spellings: te sach y lang xa hoi. hieu ((va cao) OR (va co)) tuc gia ((hanh vi) or (thanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y lang xa hoi. hieu ((va cao) OR (va co)) tuc gia ((hanh vi) OR (thanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y lang xa hoi. hieu ((va cao) OR (va co)) tuc gia ((hanh vi) or (thanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y lang xa hoi. hieu ((va cao) OR (va co)) tuc gia ((hanh vi) or (thanh va)) cua tre*.
