• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (so sach)) hay lang xay hoi. hieu ve cam xuc va lanh hai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (so sach)) hay lang xay hoi. hieu ve cam xuc va lanh hai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (so sach)) hay lang xay hoi. hieu ve cam xuc va lanh hai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (so sach)) hay lang xay hoi. hieu ve cam xuc va lanh hai ((cua tre) OR (cua triet))*.
