Perhaps you should try some spelling variations:
decrease buried » decrease burden (Expand search), decrease during (Expand search), decrease observed (Expand search)
decrease that » decrease at (Expand search), decrees that (Expand search), decree that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
buried object » buried objects (Expand search), based object (Expand search), marked object (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)

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

• Removing quotes may allow a broader search: (( decrease the decrease that decrease ) OR ( decrease NOT decrease buried object ))~.
