A sua pesquisa - ((communication documentation) OR (communication conversation)) formal erosion control right* - não corresponde a nenhum registo.

Talvez deva tentar algumas variações de ortografia:
communication documentation » communication foundation, communication communication
communication conversation » communication information, communication cohesion, communication communication
formal erosion » formal decision, local erosion, formal notion
control right » control rights, control light, control flight

Pode obter mais resultados ajustando a pesquisa.
