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