• Performing a fuzzy search may retrieve terms with similar spellings: thu sang ky nang ((x hoi) or (o hoi)). hieu ((ve cam) OR (ve cham)) duc va thanh thai cua chu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sang ky nang ((x hoi) OR (o hoi)). hieu ((ve cam) OR (ve cham)) duc va thanh thai cua chu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sang ky nang ((x hoi) or (o hoi)). hieu ((ve cam) OR (ve cham)) duc va thanh thai cua chu".
• Adding a wildcard symbol may retrieve word variants: thu sang ky nang ((x hoi) or (o hoi)). hieu ((ve cam) OR (ve cham)) duc va thanh thai cua chu*.
