Perhaps you should try some spelling variations:
decrease lodging » decrease owing (Expand search), decrease during (Expand search), decrease walking (Expand search)
lodging object » moving object (Expand search), housing object (Expand search), merging object (Expand search)
decrease flow » decreases flow (Expand search), decrease low (Expand search), decrease food (Expand search)
flow decrease » flow increase (Expand search), to decrease (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 flow decrease _ decrease ) OR ( decrease akt decrease lodging object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease flow decrease _ decrease ) OR ( decrease akt decrease lodging object ))*.
