Perhaps you should try some spelling variations:
largest decrease » largest decreases (Expand Search), marked decrease (Expand Search)
larger decrease » marked decrease (Expand Search)
_ largest » _ large (Expand Search)
ct larger » _ larger (Expand Search), c large (Expand Search)
i race » _ race (Expand Search), 3 race (Expand Search)
a rate » _ rate (Expand Search), a rare (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 race) OR (a rate)) increased ) OR ((( _ largest decrease ) OR ( ct larger decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( ((i race) OR (a rate)) increased ) OR ((( _ largest decrease ) OR ( ct larger decrease ))))*.
