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
evidence network » science network, guidance network, dence network
systems report » system report, systems support, systems recent
science where » science what
grid network » grid networks, hybrid network, world network
health grid » health guide, health guido, health gis

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