• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) OR (v nang)) ((dai hoi) or (dai moi)). hieu va cam xuc ban thanh toan cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (v nang)) ((dai hoi) OR (dai moi)). hieu va cam xuc ban thanh toan cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (v nang)) ((dai hoi) or (dai moi)). hieu va cam xuc ban thanh toan cau tren".
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) OR (v nang)) ((dai hoi) or (dai moi)). hieu va cam xuc ban thanh toan cau tren*.
