Perhaps you should try some spelling variations:
networks synthesis » network synthesis, networks systems, nets synthesis
evidence network » dence network, incidence networks, resilience network
guidance network » guide network, impedance network, guided network
science network » sciences network, science networks, science work
health incident » health including
finance network » financial network, distance network, finance work
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 ((evidence network) OR (science network)) synthesis report ) OR ( ((health science) OR (health incident)) networks synthesis report ))) OR ( health ((guidance network) OR (finance network)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health ((evidence network) OR (science network)) synthesis report ) or ( ((health science) or (health incident)) networks synthesis report ))) or ( health ((guidance network) or (finance network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health ((evidence network) OR (science network)) synthesis report ) or ( ((health science) or (health incident)) networks synthesis report ))) or ( health ((guidance network) or (finance network)) synthesis report ))*.
