Perhaps you should try some spelling variations:
replacing objects » placing objects (Expand search), reaching objects (Expand search), teaching objects (Expand search)
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)
decrease may » decrease at (Expand search), decrease by (Expand search), decrease human (Expand search)
may decrease » may increase (Expand search), can decrease (Expand search), to decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (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 may decrease NOT decrease ) OR ( decrease their decrease replacing objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease may decrease not decrease ) OR ( decrease their decrease replacing objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease may decrease not decrease ) OR ( decrease their decrease replacing objects ))*.
