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