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