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