Perhaps you should try some spelling variations:
resistance network » reluctance network, resistance new, resistance between
substance network » distance network, substrate network, guidance network
distance networks » distance network, state networks, alliance networks
health resistance » heat resistance, health assistance, earth resistance
evidence network » science network, guidance network, incidence networks
systems report » system report, systems support, systems recent
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) OR (distance networks)) systems report ) OR ( health resistance network systems report )))).
• 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) or (distance networks)) systems report ) or ( health resistance network systems report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health ((evidence network) OR (dence network)) synthesis report ) or ((( health ((substance network) or (distance networks)) systems report ) or ( health resistance network systems report ))))*.
