Perhaps you should try some spelling variations:
substance network » distance network, substrate network, resistance network
evidence network » incidence networks, resilience network, reference network
guidance network » guide network, finance network, impedance network
science network » sciences network, science networks, science work
systems report » system report, systems support, systems recent
dence network » dense network, defence network, dense networks
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 ((((evidence network) OR (guidance network))) OR (science network)) systems report\") or (\"health dence network systems report\"))) or (\"health substance network synthesis report\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"health ((((evidence network) OR (guidance network))) or (science network)) systems report\\") or (\\"health dence network systems report\\"))) or (\\"health substance network synthesis report\\"))\"".
• Removing quotes may allow a broader search: (((( health ((((evidence network) OR (guidance network))) or (science network)) systems report ) or ( health dence network systems report ))) or ( health substance network synthesis report )).
