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