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