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