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