• 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 finance network systems report") OR ("Health finance work systems report"))))) OR ("health guidance network synthesis 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 finance network systems report\") OR (\"Health finance work systems report\"))))) or (\"health guidance network synthesis report\"))))".
• Removing quotes may allow a broader search: (( health evidence network synthesis report ) or ((((( health finance network synthesis report ) or ((( Health finance network systems report ) OR ( Health finance work systems report ))))) or ( health guidance network synthesis report )))).
• Adding a wildcard symbol may retrieve word variants: (("health evidence network synthesis report") or ((((("health finance network synthesis report") or ((("Health finance network systems report") OR ("Health finance work systems report"))))) or ("health guidance network synthesis report"))))*.
