• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease may decrease any decrease ) OR ( ((decrease toc) OR (decrease of)) decrease 1 basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease may decrease any decrease ) OR ( ((decrease toc) OR (decrease of)) decrease 1 basic ))*.
