• Performing a fuzzy search may retrieve terms with similar spellings: tu sach tu hanh xa hoi. ((hieu ve) or (hieu va)) cam xuc ((va thanh) OR (ban thanh)) tai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach tu hanh xa hoi. ((hieu ve) OR (hieu va)) cam xuc ((va thanh) OR (ban thanh)) tai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach tu hanh xa hoi. ((hieu ve) or (hieu va)) cam xuc ((va thanh) OR (ban thanh)) tai cau treo*".
