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