• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease any decrease food decrease ) OR ( decrease NOT increase owing process ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease any decrease food decrease ) OR ( decrease not increase owing process ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease any decrease food decrease ) OR ( decrease not increase owing process ))*.
