• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu nang ((o hoi) or (o lai)). hieu van cam xuc van ((hanh lai) OR (thanh lap)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu nang ((o hoi) OR (o lai)). hieu van cam xuc van ((hanh lai) OR (thanh lap)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu nang ((o hoi) or (o lai)). hieu van cam xuc van ((hanh lai) OR (thanh lap)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach tu nang ((o hoi) or (o lai)). hieu van cam xuc van ((hanh lai) OR (thanh lap)) cua tre*.
