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