• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yan wang) OR (yang yang)) out test ((((yan tin) or (yuan ting))) or (wang lin)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yan wang) OR (yang yang)) out test ((((yan tin) OR (yuan ting))) OR (wang lin)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yan wang) OR (yang yang)) out test ((((yan tin) or (yuan ting))) or (wang lin)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yan wang) OR (yang yang)) out test ((((yan tin) or (yuan ting))) or (wang lin)) hong yu ;*.
