• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreased levels decrease bone processes ) OR ( python AND methods con programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased levels decrease bone processes ) OR ( python AND methods con programming ))*.
