tranh cua » doanh cua, manh cua
cua khong » hua khong, cua phuong, cua thuong
ho trieu » mot trieu, 30 trieu, ho chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (25 trieu)) tinh - canh tranh cua khong thong sang ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - canh tranh cua khong thong sang ((toan tap) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - canh tranh cua khong thong sang ((toan tap) or (toan ban))*.
