• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - manh ((trung tuan) OR (trung tam)) bang cong lang ((thang cau) OR (thong cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - manh ((trung tuan) or (trung tam)) bang cong lang ((thang cau) OR (thong cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - manh ((trung tuan) or (trung tam)) bang cong lang ((thang cau) OR (thong cau))*.
