Perhaps you should try some spelling variations:
prosecution proceedings » prosecution's proceeding (Expand search), execution proceedings (Expand search), execution proceeding (Expand search)
decrease prosecution » decreased production (Expand search), decrease predation (Expand search), decrease prevention (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to 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 _ decrease prosecution proceedings ) OR ( decrease at decrease of decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease prosecution proceedings ) OR ( decrease at decrease of decrease ))*.
