Perhaps you should try some spelling variations:
"5 we decrease" » "5 _ decrease" (Expand Search), "_ we decrease" (Expand Search)
"45 c decrease" » "45 _ decrease" (Expand Search), "45 _ decreased" (Expand Search), "45 _ decreases" (Expand Search)
"50 a decrease" » "50 _ decrease" (Expand Search), "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search), "50 i decrease" (Expand Search)
"5 a decrease" » "5 _ decrease" (Expand Search), "5 _ decreased" (Expand Search), "5 _ decreases" (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: "((\"45 c decrease\") OR (((((\"50 a decrease\") OR (\"5 a decrease\"))) OR (\"5 we decrease\"))))~".
• Removing quotes may allow a broader search: (( 45 c decrease ) OR ((((( 50 a decrease ) OR ( 5 a decrease ))) OR ( 5 we decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("45 c decrease") OR ((((("50 a decrease") OR ("5 a decrease"))) OR ("5 we decrease"))))*.
