Perhaps you should try some spelling variations:
distance networks » resistance network, state networks, alliance networks
network synthesis » network systems
distance network » resistance network, disease network, finance network
health science » health sciences

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