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