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