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