Perhaps you should try some spelling variations:
network synthesis » network systems
networked systems » network systems
health incidence » death incidence, health evidence, path incidence
networks systems » network systems, networks system, network system
science network » sciences network, science networks, science work
health incident » health including
health guidance » health evidence, health finance
health science » health sciences

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 science network synthesis report ) OR ( ((health incidence) OR (health incident)) ((networks systems) OR (networked systems)) report ))) OR ( ((health guidance) OR (health substance)) network synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health science network synthesis report ) or ( ((health incidence) or (health incident)) ((networks systems) or (networked systems)) report ))) or ( ((health guidance) OR (health substance)) network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health science network synthesis report ) or ( ((health incidence) or (health incident)) ((networks systems) or (networked systems)) report ))) or ( ((health guidance) OR (health substance)) network synthesis report ))*.
