Perhaps you should try some spelling variations:
"c larger decrease" » "c marked decrease" (Expand Search), "_ larger decrease" (Expand Search), "c large decrease" (Expand Search), "_ large decrease" (Expand Search)
"i large decrease" » "i marked decrease" (Expand Search), "i large increases" (Expand Search), "i large degree" (Expand Search), "_ large decrease" (Expand Search), "a large decrease" (Expand Search), "via large decrease" (Expand Search)
"a marked increase" » "a marker increase" (Expand Search), "_ marked increase" (Expand Search), "a market increase" (Expand Search), "a marked increased" (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: "((((\"a marked increase\") OR (\"i large decrease\"))) OR (\"c larger decrease\"))~".
• Removing quotes may allow a broader search: (((( a marked increase ) OR ( i large decrease ))) OR ( c larger decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((("a marked increase") OR ("i large decrease"))) OR ("c larger decrease"))*.
