transport air » transport a, transport data, transport _
2 leadership » 3 leadership, 4 leadership
crisis 3 » crisis _, crisis 1
crisis a » crisis _
guias 2 » guias de
guias 6 » guias de
6 smoke » _ smoke, 4 smoke, 7 smoke
air a » air _, ai a

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: (( guias 2 leadership transform ((crisis 3) OR (crisis a)) ) OR ( guias 6 smoke transport air a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias 2 leadership transform ((crisis 3) OR (crisis a)) ) or ( guias 6 smoke transport air a ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias 2 leadership transform ((crisis 3) OR (crisis a)) ) or ( guias 6 smoke transport air a ))*.
