• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ((ky dang) OR (ky danh)) xay hoi. hieu ve cam ((xuc van) or (duc minh)) hanh de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ((ky dang) OR (ky danh)) xay hoi. hieu ve cam ((xuc van) OR (duc minh)) hanh de cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky dang) OR (ky danh)) xay hoi. hieu ve cam ((xuc van) or (duc minh)) hanh de cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sai ((ky dang) OR (ky danh)) xay hoi. hieu ve cam ((xuc van) or (duc minh)) hanh de cua triet*.
