Perhaps you should try some spelling variations:
execution procedure » extraction procedure (Expand search), execution process (Expand search), execution proceedings (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
case execution » the execution (Expand search), and execution (Expand search), pre execution (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
during case » during care (Expand search), during cane (Expand search), during cadet (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 case execution procedure ) OR ( decrease akt decrease NOT decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during case execution procedure ) OR ( decrease akt decrease NOT decrease ))*.
