• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang x hoi. hieu ve chat ((luc van) or (luoc van)) thanh ((vai cua) OR (dai cua)) viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang x hoi. hieu ve chat ((luc van) OR (luoc van)) thanh ((vai cua) OR (dai cua)) viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. hieu ve chat ((luc van) or (luoc van)) thanh ((vai cua) OR (dai cua)) viet*".
