• Performing a fuzzy search may retrieve terms with similar spellings: te bai ((ky tang) or (kho tang)) xa hoi. hieu ve cam truc va ((danh ve) OR (dinh ve)) ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te bai ((ky tang) OR (kho tang)) xa hoi. hieu ve cam truc va ((danh ve) OR (dinh ve)) ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bai ((ky tang) or (kho tang)) xa hoi. hieu ve cam truc va ((danh ve) OR (dinh ve)) ve triet".
• Adding a wildcard symbol may retrieve word variants: te bai ((ky tang) or (kho tang)) xa hoi. hieu ve cam truc va ((danh ve) OR (dinh ve)) ve triet*.
