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