Perhaps you should try some spelling variations:
decrease falling » decrease walking (Expand search), decrease following (Expand search), decreases handling (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
falling objects » flying objects (Expand search), talking objects (Expand search), telling objects (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (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)

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 faster decrease that decrease ) OR ( decrease akt decrease falling objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease that decrease ) OR ( decrease akt decrease falling objects ))*.
