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