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