tien manh » tien anh, tien thanh, tieng anh
tranh cua » doanh cua, manh cua
hang nong » thang long, han tong
cua hang » cua dang, cua nhung, cua cong

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu manh) OR (tien manh)) - canh tranh cua hang nong dan ((phan lap) OR (phan tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) OR (tien manh)) - canh tranh cua hang nong dan ((phan lap) or (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) OR (tien manh)) - canh tranh cua hang nong dan ((phan lap) or (phan tu))*.
