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