• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang dong) OR (wang jing))) or (wang yang)) ((yang di) or (yang xi)) best win when using sar ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang dong) OR (wang jing))) OR (wang yang)) ((yang di) OR (yang xi)) best win when using sar ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang dong) OR (wang jing))) or (wang yang)) ((yang di) or (yang xi)) best win when using sar ;".
• Adding a wildcard symbol may retrieve word variants: ((((wang dong) OR (wang jing))) or (wang yang)) ((yang di) or (yang xi)) best win when using sar ;*.
