• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang ((x hoi) OR (o hoi)). hieu ((ve cham) or (va cham)) soc manh hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((x hoi) OR (o hoi)). hieu ((ve cham) OR (va cham)) soc manh hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((x hoi) OR (o hoi)). hieu ((ve cham) or (va cham)) soc manh hanh vai cua te*".
