• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang ya) or (yang ka))) or (yang di))ng ya human gene tang amin ((hong guan) OR (hong tan)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang ya) OR (yang ka))) OR (yang di))ng ya human gene tang amin ((hong guan) OR (hong tan)) ;.

• Adding a wildcard symbol may retrieve word variants: ((((yang ya) or (yang ka))) or (yang di))ng ya human gene tang amin ((hong guan) OR (hong tan)) ;*.
