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