• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ((ky sang) OR (ky nang)) ((ma hoi) or (mai hoi)). hieu so chao tu va thanh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky nang)) ((ma hoi) OR (mai hoi)). hieu so chao tu va thanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) OR (ky nang)) ((ma hoi) or (mai hoi)). hieu so chao tu va thanh vi cua tu".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) OR (ky nang)) ((ma hoi) or (mai hoi)). hieu so chao tu va thanh vi cua tu*.
