Perhaps you should try some spelling variations:
networks synthesis » networks systems, nets synthesis
network synthesis » network systems
health incidence » health incident, health science, health evidence
sequence network » sequence networks, science network, sequential network
guidance network » finance network, impedance network, guided network
death incidence » growth incidence, dengue incidence, graphs incidence
health sequence » health sequelae, heart sequence, health consequence
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) OR (death incidence)) networks synthesis report ) OR ( health sequence network synthesis report ))) OR ( health ((guidance network) OR (guide 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 ( health sequence network synthesis report ))) or ( health ((guidance network) or (guide network)) synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( ((health incidence) OR (death incidence)) networks synthesis report ) or ( health sequence network synthesis report ))) or ( health ((guidance network) or (guide network)) synthesis report ))*.
