• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in diseases copd processes ) OR ( python code with python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in diseases copd processes ) OR ( python code with python programming ))*.
