Talvez deva tentar algumas variações de ortografia:
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease and (Expandir a busca)
on decrease » on decreased (Expandir a busca), of decrease (Expandir a busca), and decrease (Expandir a busca)
decrease or » decrease of (Expandir a busca), decrease pro (Expandir a busca), decrease toc (Expandir a busca)
or decrease » of decrease (Expandir a busca), not decrease (Expandir a busca), to decrease (Expandir a busca)
mask object » mass objects (Expandir a busca), dark object (Expandir a busca), based object (Expandir a busca)
task object » dark object (Expandir a busca), disk object (Expandir a busca), tasks subject (Expandir a busca)

• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: (( decrease on decrease _ decrease ) OR ( decrease OR decrease ((mask object) OR (task object)) ))~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( decrease on decrease _ decrease ) OR ( decrease or decrease ((mask object) OR (task object)) ))~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( decrease on decrease _ decrease ) OR ( decrease or decrease ((mask object) OR (task object)) ))*.
