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