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