Perhaps you should try some spelling variations:
network synthesis » network systems
guidance network » finance network, impedance network, guided network
evidence network » incidence networks, resilience network, reference network
science network » sciences network, science networks, science work
systems support » system support, systems supporting, system supporting
health guidance » health evidence, health finance, health substance
systems report » system report, systems recent, systems transport
dence network » dense network, defence network, dense networks
guide network » guided network, wide network, inside network
side network » wide network, inside network, mode 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 (systems support)) ) OR ((( health guidance network synthesis report ) OR ( health ((guide network) OR (side 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 (systems support)) ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (side network)) synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((((evidence network) OR (dence network))) or (science network)) ((systems report) or (systems support)) ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (side network)) synthesis report ))))*.
