Perhaps you should try some spelling variations:
substance network » distance network, resistance network, distance networks
substrate network » subscribe networks, subscriber network, state network
health resistance » health assistance, earth resistance, health resilience
evidence network » science network, guidance network, dence network
health evidence » health science
heat resistance » least resistance, host resistance, heat resistant
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) OR (substrate network)) systems report ) OR ( ((health resistance) OR (heat 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) or (substrate network)) systems report ) or ( ((health resistance) OR (heat resistance)) network systems report ))))".
• Adding a wildcard symbol may retrieve word variants: (( health evidence network synthesis report ) or ((( health ((substance network) or (substrate network)) systems report ) or ( ((health resistance) OR (heat resistance)) network systems report ))))*.
