Perhaps you should try some spelling variations:

nn decrease » _ decrease (Expand Search), a decrease (Expand Search), gy decreased (Expand Search)
we decrease » _ decrease (Expand Search), a decrease (Expand Search), teer decrease (Expand Search)
c decrease » c decreased (Expand Search), _ decrease (Expand Search), a decrease (Expand Search)
50 mean » 20 means (Expand Search)
50 nn » 50 ns (Expand Search), 50 ng (Expand Search), 50 n (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: "(( 5 c decrease ) OR ((((( 50 nn decrease ) OR ( 50 mean decrease ))) OR ( 50 we decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( 5 c decrease ) OR ((((( 50 nn decrease ) OR ( 50 mean decrease ))) OR ( 50 we decrease ))))*.
