Perhaps you should try some spelling variations:
execution proceeding » execution proceedings (Expand search), execution procedure (Expand search), executive processing (Expand search)
decree execution » degree executive (Expand search), decreto executivo (Expand search), between execution (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decree » farming decree (Expand search), during three (Expand search), during dengue (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

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: "(( decrease during decree execution proceeding ) OR ( decrease to decrease in decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during decree execution proceeding ) OR ( decrease to decrease in decrease ))*.
