• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ky nang o hoi. hieu ve cam tuc ban hang ((vi cua) or (((vai cua) OR (dai cua)))) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky nang o hoi. hieu ve cam tuc ban hang ((vi cua) OR (((vai cua) OR (dai cua)))) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky nang o hoi. hieu ve cam tuc ban hang ((vi cua) or (((vai cua) OR (dai cua)))) triet*".
