Perhaps you should try some spelling variations:
network synthesis » network systems
evidence network » incidence networks, resilience network, reference network
guidance network » finance network, impedance network, distance network
science network » sciences network, science networks, science work
systems report » system report, systems support, systems recent
dence network » dense network, defence network, dense networks
guide network » side network, wide network, inside network
health guide » health guido, earth guide, health grid

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