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