Perhaps you should try some spelling variations:
resistance network » reluctance network, resistance new, resistance between
network synthesis » network systems
substance network » distance network, substrate network, distance networks
health resistance » heat resistance, health assistance, earth resistance
systems report » system report, systems support, systems transport
dence network » dense network, defence network, dense networks
health dence » health device, health evidence, health science

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 synthesis report ) OR ((( health substance network ((systems report) OR (systems recent)) ) OR ( health resistance network ((systems report) OR (systems recent)) )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( health dence network synthesis report ) or ((( health substance network ((systems report) OR (systems recent)) ) or ( health resistance network ((systems report) OR (systems recent)) ))))".
• Adding a wildcard symbol may retrieve word variants: (( health dence network synthesis report ) or ((( health substance network ((systems report) OR (systems recent)) ) or ( health resistance network ((systems report) OR (systems recent)) ))))*.
