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