• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) or (chieu xanh)) - thanh trong tuan duong cong ((toan khoan) OR (toan hoat)) cam~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chieu xanh)) - thanh trong tuan duong cong ((toan khoan) OR (toan hoat)) cam*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu xanh)) - thanh trong tuan duong cong ((toan khoan) OR (toan hoat)) cam*".
