Perhaps you should try some spelling variations:
infrastructure politics » infrastructural politics, infrastructure policies, infrastructure utilities
infrastructure policy » infrastructure project, infrastructure projects
scale infrastructure » scalable infrastructure, secure infrastructure, core infrastructure
space infrastructure » service infrastructure, storage infrastructure, science infrastructure

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: (( ((scale infrastructure) OR (space infrastructure)) policies ) OR ( smart ((infrastructure politics) OR (infrastructure policy)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((scale infrastructure) or (space infrastructure)) policies ) or ( smart ((infrastructure politics) OR (infrastructure policy)) ))".
• Adding a wildcard symbol may retrieve word variants: (( ((scale infrastructure) or (space infrastructure)) policies ) or ( smart ((infrastructure politics) OR (infrastructure policy)) ))*.
