Perhaps you should try some spelling variations:
incidence networks » inference networks, influence networks, incidents network
networked systems » network systems
health incidence » death incidence, health incident, health evidence
science networks » science network, sciences network, sequence networks
guidance network » guide network, finance network, guided network
health science » health sciences

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