transform fft » transform tvdft, transform cote, transform test
own leaders » born leaders, own leadership, women leaders
transfer 3 » transfer _, transfer 4, transfer a
guias f » guias de
f gases » _ gases
fft 4 » aft 4, fat 4, fft _
3 ao » 3 a, 3 co, 3 do

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: (( areas ((own leaders) OR (known leaders)) transform fft 4 ) OR ( guias f gases transfer 3 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas ((own leaders) OR (known leaders)) transform fft 4 ) or ( guias f gases transfer 3 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas ((own leaders) OR (known leaders)) transform fft 4 ) or ( guias f gases transfer 3 ao ))*.
