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