Perhaps you should try some spelling variations:
guidance network » finance network, impedance network, guided network
sequence network » sequence networks, sequential network, recurrence network
science network » sciences network, science networks, science work
systems report » system report, systems support, systems recent
heart sequence » heart sequences, charts sequence, header sequence
dence network » dense network, defence network, dense networks
guide network » guided network, side network, wide network

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 ((dence network) OR (science network)) systems report ) OR ( heart sequence network systems report ))) OR ( health ((guidance network) OR (guide network)) systems report )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( health ((dence network) or (science network)) systems report ) or ( heart sequence network systems report ))) or ( health ((guidance network) OR (guide network)) systems report ))".
• Adding a wildcard symbol may retrieve word variants: (((( health ((dence network) or (science network)) systems report ) or ( heart sequence network systems report ))) or ( health ((guidance network) OR (guide network)) systems report ))*.
