Perhaps you should try some spelling variations:
networks synthesis » networks systems
network synthesis » network systems
health incidence » death incidence, health incident, health science
sequence network » sequence networks, science network, sequential network
guidance network » guide network, finance network, impedance network
health sequence » health sequelae, heart sequence, health consequence
health guidance » health evidence, health finance, health substance
nets synthesis » net synthesis, dots synthesis, its synthesis

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 sequence network synthesis report ))) OR ( health guidance 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 sequence network synthesis report ))) or ( health guidance network synthesis report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health incidence ((networks synthesis) OR (nets synthesis)) report ) or ( health sequence network synthesis report ))) or ( health guidance network synthesis report ))*.
