Perhaps you should try some spelling variations:
network synthesis » network systems
defense networks » defense network, dense networks, defenses network
guidance network » guide network, finance network, impedance network
science network » sciences network, science networks, science work
defence network » defense network, defenses network, reference network
health guidance » health evidence, health finance, health substance
health science » health sciences
dence network » dense network, dense networks, device 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) OR (defense networks)) synthesis report ))))) OR ( health guidance 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) OR (defense networks)) synthesis report ))))) or ( health guidance 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) OR (defense networks)) synthesis report ))))) or ( health guidance network synthesis report ))*.
