• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky ((lang xa) OR (lang van)) hoi. ((hieu ve) or (lieu va)) cau tu xa hanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang xa) OR (lang van)) hoi. ((hieu ve) OR (lieu va)) cau tu xa hanh lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky ((lang xa) OR (lang van)) hoi. ((hieu ve) or (lieu va)) cau tu xa hanh lai cua triet".
