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, guided network
science network » sciences network, science networks, science work
health guidance » health evidence, health finance, health substance
systems report » system report, systems support, systems recent
dence network » dense network, defence network, dense networks
guide network » guided network, inside network, bridge network
side network » inside network, mode network, fine network
wide network » mode network, fine network, node 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 ((((evidence network) OR (dence network))) OR (science network)) systems report ) OR ((( health guidance network synthesis report ) OR ( health ((guide network) OR (((side network) OR (wide 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 synthesis report ) or ( health ((guide network) or (((side network) OR (wide 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 synthesis report ) or ( health ((guide network) or (((side network) OR (wide network)))) synthesis report ))))*.
