• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease can ((decrease toc) OR (decrease of)) decrease ) OR ( decrease OR decrease owing in ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease can ((decrease toc) OR (decrease of)) decrease ) OR ( decrease or decrease owing in ))~".
