Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search)
latest decrease » greatest decrease (Expand Search), largest decreases (Expand Search), latency decreased (Expand Search)
marked decrease » marked increase (Expand Search)
large decrease » larger decrease (Expand Search), large increases (Expand Search), large degree (Expand Search)
a large » _ large (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: "(( a large decrease ) OR ( a ((((latest decrease) OR (largest decrease))) OR (marked decrease)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( a large decrease ) OR ( a ((((latest decrease) OR (largest decrease))) OR (marked decrease)) ))*.
