Perhaps you should try some spelling variations:
network synthesis » network systems
science networks » sciences network, sequence networks, science works
guidance network » finance network, impedance network, guided network
science network » sciences network, science work, sequence networks
health guidance » health evidence, health finance, health substance
systems report » systems support, 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 ((dence network) OR (((science network) OR (science networks)))) ((systems report) OR (system report)) ) 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 ((dence network) or (((science network) or (science networks)))) ((systems report) OR (system report)) ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (side network)) synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((dence network) or (((science network) or (science networks)))) ((systems report) OR (system report)) ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (side network)) synthesis report ))))*.
