Perhaps you should try some spelling variations:
network synthesis » network systems
guidance network » guide network, impedance network, guided network
finance network » financial network, distance network, finance work
health devices » health device, health services, health service
dence network » dense network, defence network, dense networks
health dence » health device, health evidence, health science

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 dence network synthesis report ) OR ( ((health dence) OR (health devices)) network 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 dence network synthesis report ) or ( ((health dence) or (health devices)) network synthesis report ))) or ( health ((guidance network) OR (finance network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health dence network synthesis report ) or ( ((health dence) or (health devices)) network synthesis report ))) or ( health ((guidance network) OR (finance network)) synthesis report ))*.
