• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (bien tinh)) - anh ((hoan cua) OR (han cua)) tong cong san toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (bien tinh)) - anh ((hoan cua) OR (han cua)) tong cong san toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (bien tinh)) - anh ((hoan cua) OR (han cua)) tong cong san toan cao*.
