Perhaps you should try some spelling variations:
"_ we decrease" » "_ _ decrease" (Expand Search), "_ web decrease" (Expand Search), "_ e decrease" (Expand Search), "_ fe decrease" (Expand Search)
"50 a decrease" » "50 _ decrease" (Expand Search), "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search)
"5 a decrease" » "5 _ decrease" (Expand Search), "5 _ decreased" (Expand Search), "5 _ decreases" (Expand Search)
"50 i decrease" » "50 _ decrease" (Expand Search), "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search), "10 i decrease" (Expand Search), "5 i 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 a decrease\") OR (\"5 a decrease\"))) OR (\"50 i decrease\"))) OR (\"_ we decrease\"))~".
• Removing quotes may allow a broader search: (((((( 50 a decrease ) OR ( 5 a decrease ))) OR ( 50 i decrease ))) OR ( _ we decrease ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("50 a decrease") OR ("5 a decrease"))) OR ("50 i decrease"))) OR ("_ we decrease"))*.
