Perhaps you should try some spelling variations:
decrease housing » decrease during (Expand search), decrease lodging (Expand search), decrease owing (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
housing object » using object (Expand search), housing project (Expand search), moving object (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)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease akt decrease faster decrease ) OR ( decrease to decrease housing object ))~.
