Perhaps you should try some spelling variations:
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » stress decreases (Expand search)
decrease when » decrease the (Expand search), decreases wheat (Expand search), decrease their (Expand search)
when object » when objects (Expand search), when subject (Expand search), en object (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 _ decrease ) OR ( decrease strain decrease when object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease _ decrease ) OR ( decrease strain decrease when object ))*.
