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

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