Perhaps you should try some spelling variations:
networks synthesis » networks systems
network synthesis » network systems
health incidence » death incidence, health incident, health science
guidance network » impedance network, guided network, science network
finance network » financial network, distance network, finance work
nets synthesis » net synthesis, dots synthesis, its synthesis
health finance » health financing, health insurance
guide network » guided network, side network, wide network

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 synthesis) OR (nets synthesis)) report\") or (((\"health ((guidance network) OR (guide network)) synthesis report\") or (\"health finance network synthesis report\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"health incidence ((networks synthesis) OR (nets synthesis)) report\\") or (((\\"health ((guidance network) or (guide network)) synthesis report\\") or (\\"health finance network synthesis report\\"))))\"".
• Removing quotes may allow a broader search: (( health incidence ((networks synthesis) OR (nets synthesis)) report ) or ((( health ((guidance network) or (guide network)) synthesis report ) or ( health finance network synthesis report )))).
