Perhaps you should try some spelling variations:
decrease buffer » decrease after (Expand search), decrease burden (Expand search), decrease suffering (Expand search)
buffer objects » buffer effects (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (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)

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 with decrease at decrease ) OR ( decrease NOT decrease buffer objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease with decrease at decrease ) OR ( decrease NOT decrease buffer objects ))*.
