• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) OR (chieu sang)) - hanh trung ((tam khong) or (tao khong)) dang manh toan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - hanh trung ((tam khong) OR (tao khong)) dang manh toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - hanh trung ((tam khong) or (tao khong)) dang manh toan ban".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - hanh trung ((tam khong) or (tao khong)) dang manh toan ban*.
