Perhaps you should try some spelling variations:
network synthesis » network systems
finance network » financial network, distance network, guidance network
dense networks » gene networks
health finance » health financing, health insurance
dence network » dense network, defence network, device network
system report » system reform, system reforms, system recent
health guide » earth guide, health grid, health side
health guido » health gindo, health grid, health guiding

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 ((dence network) OR (dense networks)) ((system report) OR (system support)) ) OR ((( ((health guide) OR (health guido)) network synthesis report ) OR ( health finance network synthesis report )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health ((dence network) OR (dense networks)) ((system report) or (system support)) ) or ((( ((health guide) or (health guido)) network synthesis report ) or ( health finance network synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((dence network) OR (dense networks)) ((system report) or (system support)) ) or ((( ((health guide) or (health guido)) network synthesis report ) or ( health finance network synthesis report ))))*.
