Perhaps you should try some spelling variations:
resistance network » reluctance network, resistance new, resistance between
network synthesis » network systems
evidence network » science network, dence network, incidence networks
guidance network » guide network, finance network, impedance network
distance network » distance networks, disease network, finance network
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 evidence network synthesis report ) OR ( health ((guidance network) OR (((distance network) OR (resistance network)))) synthesis report )).
• Adding a wildcard symbol may retrieve word variants: (( health evidence network synthesis report ) or ( health ((guidance network) or (((distance network) or (resistance network)))) synthesis report ))*.
