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