Perhaps you should try some spelling variations:
networks synthesis » networks systems, nets synthesis
"health evidence network systems report" » "health science network systems report", "health guidance network systems report", "health dence network systems report", "health evidence network system report", "health evidence network systems support", "health evidence network systems recent"
death incidence » disease incidence, growth incidence, dengue incidence
health science » health sciences
"health gridd network synthesis report" » "health grid network synthesis report", "health guided network synthesis report", "health grid networks synthesis report", "health guido network synthesis report", "health gains network synthesis report"
"health great network synthesis report" » "health great networker synthesis report", "health green network synthesis report", "health guest network synthesis report"
"health guide network synthesis report" » "health guided network synthesis report", "health side network synthesis report", "health wide network synthesis report", "health guido network synthesis report", "earth guide network synthesis report", "health grid network synthesis report"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("health evidence network systems report") OR ("((death incidence) or (health science)) networks synthesis report"))) OR ((((("health gridd network synthesis report") OR ("health great 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 report\") or (\"((death incidence) or (health science)) networks synthesis report\"))) or (((((\"health gridd network synthesis report\") OR (\"health great network synthesis report\"))) or (\"health guide network synthesis report\"))))".
• Removing quotes may allow a broader search: (((( health evidence network systems report ) or ( ((death incidence) or (health science)) networks synthesis report ))) or ((((( health gridd network synthesis report ) OR ( health great network synthesis report ))) or ( health guide network synthesis report )))).
• Adding a wildcard symbol may retrieve word variants: (((("health evidence network systems report") or ("((death incidence) or (health science)) networks synthesis report"))) or ((((("health gridd network synthesis report") OR ("health great network synthesis report"))) or ("health guide network synthesis report"))))*.
