• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((((chieu xanh) OR (chieu sach))) OR (chieu sang)) - canh trinh va thong cong van chat va~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - canh trinh va thong cong van chat va~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu xanh) OR (chieu sach))) or (chieu sang)) - canh trinh va thong cong van chat va*.
