• Performing a fuzzy search may retrieve terms with similar spellings: ((((yan liang) OR (yang liang))) or (yan guan)) ((yuan hui) or (tuan vu)) hui yang di long du ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan liang) OR (yang liang))) OR (yan guan)) ((yuan hui) OR (tuan vu)) hui yang di long du ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan liang) OR (yang liang))) or (yan guan)) ((yuan hui) or (tuan vu)) hui yang di long du ;".
• Adding a wildcard symbol may retrieve word variants: ((((yan liang) OR (yang liang))) or (yan guan)) ((yuan hui) or (tuan vu)) hui yang di long du ;*.
