• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (so sanh)) ty hang ca hoi. hieu qua ca xuc ban thanh ((vi cua) OR (vai cua)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sanh)) ty hang ca hoi. hieu qua ca xuc ban thanh ((vi cua) OR (vai cua)) tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sanh)) ty hang ca hoi. hieu qua ca xuc ban thanh ((vi cua) OR (vai cua)) tu*".
