Perhaps you should try some spelling variations:
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 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)
art object » art objects (Expand search), smart object (Expand search), an object (Expand search)
at object » an object (Expand search), art objects (Expand search), lat objects (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 _ decrease ) OR ( decrease akt decrease ((at object) OR (art object)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease with decrease _ decrease ) OR ( decrease akt decrease ((at object) OR (art object)) ))*.
