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