• Performing a fuzzy search may retrieve terms with similar spellings: ((wang wang) or (wang yang)) ((((tan hua) OR (tuan hua))) or (wang hua)) ren yan jiu hong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yang)) ((((tan hua) OR (tuan hua))) OR (wang hua)) ren yan jiu hong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang yang)) ((((tan hua) OR (tuan hua))) or (wang hua)) ren yan jiu hong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang yang)) ((((tan hua) OR (tuan hua))) or (wang hua)) ren yan jiu hong shu ;*.
