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