two leaders » top leaders, two layers, team leaders
areas two » areas co
guias de » guia de, guide de, aguas de
pairs a » pairs _, fairs a, pairs 1

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 two leaders transform ((pairs a) OR (pairs 4)) ) OR ( guias de mais transfer _ do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas two leaders transform ((pairs a) OR (pairs 4)) ) or ( guias de mais transfer _ do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas two leaders transform ((pairs a) OR (pairs 4)) ) or ( guias de mais transfer _ do ))*.
