Talvez debería tentar con algunhas variantes ortográficas:
"observation process" » "conservation process" (Expandir procura)
"observations process" » "conservations process" (Expandir procura), "conservation process" (Expandir procura)
"conservations process" » "conservation process" (Expandir procura), "considerations process" (Expandir procura)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"observation process\") OR (((\"observations process\") OR (\"conservations process\"))))~".
• Removing quotes may allow a broader search: (( observation process ) OR ((( observations process ) OR ( conservations process ))))~.
• Adding a wildcard symbol may retrieve word variants: (("observation process") OR ((("observations process") OR ("conservations process"))))*.
