Perhaps you should try some spelling variations:
networks synthesis » network synthesis, networks systems, nets synthesis
health incidence » health incident, health science, health evidence
death incidence » disease incidence, growth incidence, dengue incidence
guide network » guided network, wide network, inside network
side network » wide network, inside network, mode 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) OR (death incidence)) networks synthesis report ) OR ( earth ((guide network) OR (side network)) synthesis report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((health incidence) or (death incidence)) networks synthesis report ) or ( earth ((guide network) OR (side network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (( ((health incidence) or (death incidence)) networks synthesis report ) or ( earth ((guide network) OR (side network)) synthesis report ))*.
