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