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