Perhaps you should try some spelling variations:
network synthesis » network systems
evidence network » guidance network, dence network, incidence networks
distance network » distance networks, resistance network, disease network
science network » sciences network, science networks, science work
finance network » financial network, guidance network, finance work
guide network » guided network, side network, wide network
health guide » health guido, earth guide, health grid

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 recent ) OR ((( health ((finance network) OR (distance network)) synthesis report ) OR ( health guide network synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((evidence network) or (science network)) systems recent ) or ((( health ((finance network) OR (distance network)) synthesis report ) or ( health guide network synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) or (science network)) systems recent ) or ((( health ((finance network) OR (distance network)) synthesis report ) or ( health guide network synthesis report ))))*.
