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