• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi thien) OR (ho chieu)) xanh - anh dung cua ((nhung cong) OR (hang cong)) dan than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi thien) or (ho chieu)) xanh - anh dung cua ((nhung cong) OR (hang cong)) dan than cau".
• Adding a wildcard symbol may retrieve word variants: ((thi thien) or (ho chieu)) xanh - anh dung cua ((nhung cong) OR (hang cong)) dan than cau*.
