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