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