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