• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using complexation with coding program\") OR (\"using mutation _ coding program\"))~".
• Removing quotes may allow a broader search: (( using complexation with coding program ) OR ( using mutation _ coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using complexation with coding program") OR ("using mutation _ coding program"))*.
