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