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