Perhaps you should try some spelling variations:
guidance network » impedance network, science network, distance network
finance network » financial network, distance network, finance work
dence network » dense network, defence network, dense networks
system report » system reform, system reforms, system recent
guide network » side network, wide network, inside network
health dence » health device, health evidence, health science

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 ((system report) OR (system support)) ) OR ((( health ((guide network) OR (guided network)) synthesis report ) OR ( health ((finance network) OR (guidance network)) synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health dence network ((system report) or (system support)) ) or ((( health ((guide network) or (guided network)) synthesis report ) or ( health ((finance network) OR (guidance network)) synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health dence network ((system report) or (system support)) ) or ((( health ((guide network) or (guided network)) synthesis report ) or ( health ((finance network) OR (guidance network)) synthesis report ))))*.
