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