Perhaps you should try some spelling variations:
network synthesis » network systems
evidence network » science network, dence network, incidence networks
guidance network » guide network, impedance network, science network
health evidence » health science
finance network » financial network, distance network, finance work

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