khach san » khach hang, thanh san
tieu tham » tieu thu, hien tham, hieu pham
lieu tham » lieu tai, lieu phap
nhan hien » nhan vien, nhan dien, han hien
ban dung » van dung, dan dung, tan dung
ket luan » ket qua, te luan, dat luan

• If you are trying to use Boolean operators, they must be ALL CAPS: ban dung ((khach luan) OR (khach san)) ket luan ((tieu tham) OR (lieu tham)) kinh doanh nhan hien~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ban dung ((khach luan) or (khach san)) ket luan ((tieu tham) OR (lieu tham)) kinh doanh nhan hien~".
• Adding a wildcard symbol may retrieve word variants: ban dung ((khach luan) or (khach san)) ket luan ((tieu tham) OR (lieu tham)) kinh doanh nhan hien*.
