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