Perhaps you should try some spelling variations:
network synthesis » network systems
defence network » defense network, defenses network, defense networks
finance network » financial network, distance network, guidance network
health finance » health financing, health insurance
dence network » dense network, dense networks, device network
system report » system reform, system support, system reforms
guide network » side network, wide network, inside network

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