Perhaps you should try some spelling variations:
network synthesis » network systems
guidance network » finance network, impedance network, guided network
science network » sciences network, science networks, science work
defence network » defense network, defenses network, defense networks
health science » health sciences
health defence » health adherence, health reference, health terrence
dence network » dense network, dense networks, device network
guide network » guided network, side network, wide network
health dence » health device, health evidence, health devices

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