Perhaps you should try some spelling variations:
incidence networks » inference networks, influence networks, science networks
network synthesis » network systems
evidence network » science network, dence network, resilience network
guidance network » guide network, finance network, impedance network
health guidance » health evidence, health finance, health substance
gis network » geis network, gis networks, nis network
health gis » health gains, health gods, health grid

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 (incidence networks)) systems recent ) OR ((( health guidance network synthesis report ) OR ( health gis network synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((evidence network) OR (incidence networks)) systems recent ) or ((( health guidance network synthesis report ) or ( health gis network synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) OR (incidence networks)) systems recent ) or ((( health guidance network synthesis report ) or ( health gis network synthesis report ))))*.
