• If you are trying to use Boolean operators, they must be ALL CAPS: (("health science network synthesis report") OR ((("health insurance network systems report") OR ("health insurance network system report"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"health science network synthesis report\") or (((\"health insurance network systems report\") OR (\"health insurance network system report\"))))*".
• Removing quotes may allow a broader search: (( health science network synthesis report ) or ((( health insurance network systems report ) OR ( health insurance network system report ))))*.
