Perhaps you should try some spelling variations:
network synthesis » network systems
evidence network » science network, guidance network, dence network
disease network » dense network
systems report » system report, systems support, systems recent
health disease » heart disease
hybrid network » hybrid networks
science work » science works, science world, science where
grid network » grid networks, world 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 work)) systems report ) OR ((( health disease network synthesis report ) OR ( health ((grid network) OR (hybrid network)) synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((evidence network) or (science work)) systems report ) or ((( health disease network synthesis report ) or ( health ((grid network) OR (hybrid network)) synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) or (science work)) systems report ) or ((( health disease network synthesis report ) or ( health ((grid network) OR (hybrid network)) synthesis report ))))*.
