Perhaps you should try some spelling variations:
networks synthesis » nets synthesis
network synthesis » network systems
health incidence » death incidence, health incident, health science
networks systems » network systems, networks system, networked systems
finance network » financial network, distance network, guidance network
health guided » health guide, hath guided, health guido

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