Perhaps you should try some spelling variations:
"50 pp decrease" » "50 _ decrease" (Expand Search)
"5 a decrease" » "5 _ decrease" (Expand Search), "5 _ decreased" (Expand Search), "5 _ decreases" (Expand Search)
"1 i decrease" » "1 _ decrease" (Expand Search), "1 _ decreased" (Expand Search), "1 _ decreases" (Expand Search)
"5 point decrease" » "_ point decrease" (Expand Search), "a point decrease" (Expand Search), "3d point 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: "((\"50 pp decrease\") OR (((((\"5 a decrease\") OR (\"5 point decrease\"))) OR (\"1 i decrease\"))))~".
• Removing quotes may allow a broader search: (( 50 pp decrease ) OR ((((( 5 a decrease ) OR ( 5 point decrease ))) OR ( 1 i decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("50 pp decrease") OR ((((("5 a decrease") OR ("5 point decrease"))) OR ("1 i decrease"))))*.
