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