• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((riveting methods) OR (existing methods))) OR (((pruning methods) OR (drying methods))))*".
• Removing quotes may allow a broader search: ((((riveting methods) OR (existing methods))) OR (((pruning methods) OR (drying methods))))*.
