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