Perhaps you should try some spelling variations:
decrease reaching » decrease replacing (Expand search), decreased reactive (Expand search), decreases reactive (Expand search)
reaching objects » teaching objects (Expand search), teaching object (Expand search), teaching subjects (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
after decrease » faster decrease (Expand search), after deceased (Expand search), litter decrease (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease with (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any 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 after decrease AND decrease ) OR ( decrease akt decrease reaching objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease after decrease AND decrease ) OR ( decrease akt decrease reaching objects ))*.
