Perhaps you should try some spelling variations:
network synthesis » network systems
evidence network » science network, guidance network, incidence networks
finance network » financial network, distance network, guidance network
health finance » health financing, health insurance
dence network » dense network, defence network, dense networks

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 (dence network)) synthesis report ) OR ( health finance network synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((evidence network) OR (dence network)) synthesis report ) or ( health finance network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) OR (dence network)) synthesis report ) or ( health finance network synthesis report ))*.
