• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - hanh ((chinh cua) OR (chinh sua)) khong cong thanh van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hanh ((chinh cua) OR (chinh sua)) khong cong thanh van ban".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hanh ((chinh cua) OR (chinh sua)) khong cong thanh van ban*.
