Perhaps you should try some spelling variations:
evidence network » science network, guidance network, incidence networks
distance network » distance networks, resistance network, disease network
dence network » dense network, defence network, dense networks
finance work » finance what

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