Perhaps you should try some spelling variations:
incidence networks » inference networks, influence networks, science networks
network synthesis » network systems
evidence network » science network, dence network, resilience network
guidance network » finance network, impedance network, guided network
health guidance » health evidence, health finance, health substance
systems report » system report, systems support, systems recent
guide network » guided network, inside network, bridge network
wide network » mode network, line network, like network
side network » inside network, mode network, line 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 (incidence networks)) systems report ) OR ((( health guidance network synthesis report ) OR ( health ((guide network) OR (((wide network) OR (side network)))) synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((evidence network) OR (incidence networks)) systems report ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (((wide network) or (side network)))) synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) OR (incidence networks)) systems report ) or ((( health guidance network synthesis report ) or ( health ((guide network) or (((wide network) or (side network)))) synthesis report ))))*.
