• Performing a fuzzy search may retrieve terms with similar spellings: ((((wang yong) OR (wang yang))) or (wang yan)) ya hiv west (ryang or ryangg) lin zong vu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yong) OR (wang yang))) OR (wang yan)) ya hiv west (ryang OR ryangg) lin zong vu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yong) OR (wang yang))) or (wang yan)) ya hiv west (ryang or ryangg) lin zong vu ;".
• Adding a wildcard symbol may retrieve word variants: ((((wang yong) OR (wang yang))) or (wang yan)) ya hiv west (ryang or ryangg) lin zong vu ;*.
