Perhaps you should try some spelling variations:
defense processes » defense process (Expand search), decrease processes (Expand search), disease processes (Expand search)
decrease defense » defense defense (Expand search), decrease release (Expand search), decreases disease (Expand search)
python classes » person classes (Expand search), python casos (Expand search), vpython colisoes (Expand search)
decrease soil » decreases soil (Expand search), increase soil (Expand search), decrease il (Expand search)
soil decrease » oil decreases (Expand search), soil increase (Expand search), soil increases (Expand search)
classes api » classe api (Expand search), classes and (Expand search), classes at (Expand search)

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

• Removing quotes may allow a broader search: (( decrease soil decrease defense processes ) OR ( python classes api python programming ))~.
