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"))))*.
