• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ((((((yang lin) OR (wang lin))) OR (yang di))) OR (yang yi)) du yang chik dong african ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((((((yang lin) OR (wang lin))) or (yang di))) or (yang yi)) du yang chik dong african ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((((((yang lin) OR (wang lin))) or (yang di))) or (yang yi)) du yang chik dong african ;*.
