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