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