nhung cong » dung cong, thong cong, hang cong
tranh cua » doanh cua, manh cua
cua nhung » va nhung

• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (nhieu tang)) - canh tranh cua nhung cong tap ((doan cau) OR (doan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (nhieu tang)) - canh tranh cua nhung cong tap ((doan cau) OR (doan dau))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (nhieu tang)) - canh tranh cua nhung cong tap ((doan cau) OR (doan dau))*.
