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