Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search)
marked decrease » marked increase (Expand Search)
i largest » _ largest (Expand Search), i large (Expand Search)
c marked » _ marked (Expand Search), a marked (Expand Search), n marked (Expand Search)
b large » _ large (Expand Search), _ larger (Expand Search)
a large » _ large (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: "(((( ((b large) OR (a large)) decrease ) OR ( c marked decrease ))) OR ( i largest decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( ((b large) OR (a large)) decrease ) OR ( c marked decrease ))) OR ( i largest decrease ))*.
