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