• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease host disease controlled process ) OR ( python code python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease host disease controlled process ) OR ( python code python python programming ))*.
