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