Perhaps you should try some spelling variations:
field processor » field processing (Expand search), field progression (Expand search), fields processing (Expand search)
decrease field » decreases yield (Expand search), increase field (Expand search), decrease cell (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
life decrease » life decreases (Expand search), life decreased (Expand search), life increase (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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease rate decrease field processor ) OR ( decrease the decrease life decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease field processor ) OR ( decrease the decrease life decrease ))*.
