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