Perhaps you should try some spelling variations:
precedence networks » preference networks, reference networks, presence networks
influence networks » inference networks, inference network, reference networks
network synthesis » network systems
science networks » science network, sciences network, sequence networks
guidance network » guide network, finance network, impedance network
health guidance » health evidence, health finance, health substance

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 ((((precedence networks) OR (science networks))) OR (influence networks)) synthesis report ) OR ( health guidance network synthesis report )).
• Adding a wildcard symbol may retrieve word variants: (( health ((((precedence networks) or (science networks))) or (influence networks)) synthesis report ) or ( health guidance network synthesis report ))*.
