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, dence network
health evidence » health science
systems report » system report, systems support, systems recent

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