• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wan wang) OR (yan wang))) OR (yuan wang)) yan zi chen zhen ((ein von) OR (erwin von)) seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan wang) or (yan wang))) or (yuan wang)) yan zi chen zhen ((ein von) OR (erwin von)) seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan wang) or (yan wang))) or (yuan wang)) yan zi chen zhen ((ein von) OR (erwin von)) seo ;*.
