Perhaps you should try some spelling variations:
network synthesis » network systems
health impedance » health importance, health temperance, head impedance
finance network » financial network, distance network, guidance network
systems report » system report, systems support, systems transport
health finance » health financing, health insurance
dence network » dense network, defence network, device 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 ((dence network) OR (dense networks)) systems report ) OR ( health ((dence network) OR (dense networks)) systems recent ))) OR ((( health impedance 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)) systems report ) or ( health ((dence network) OR (dense networks)) systems recent ))) or ((( health impedance network synthesis report ) or ( health finance network synthesis report ))))".
• Adding a wildcard symbol may retrieve word variants: (((( health ((dence network) OR (dense networks)) systems report ) or ( health ((dence network) OR (dense networks)) systems recent ))) or ((( health impedance network synthesis report ) or ( health finance network synthesis report ))))*.
