Perhaps you should try some spelling variations:
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
and decreased » and decreases (Expand search), and increased (Expand search)
decrease cost » decrease costs (Expand search), decreases post (Expand search), decreasing cost (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decreased at » decreased akt (Expand search), decreased ant (Expand search), decrease at (Expand search)
cost objects » lost objects (Expand search), lost object (Expand search), iot objects (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease AND decreased at decrease ) OR ( decrease their decrease cost objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decreased at decrease ) OR ( decrease their decrease cost objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decreased at decrease ) OR ( decrease their decrease cost objects ))*.
