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