Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), defense processes (Expand search), decay processes (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decrease sucrose (Expand search)
fields decrease » cells decrease (Expand search), field increase (Expand search)
