Perhaps you should try some spelling variations:
"50 ms decrease" » "50 _ decrease" (Expand Search)
"5 nm decrease" » "5 _ decrease" (Expand Search), "6 nm decrease" (Expand Search)
"_ fe decrease" » "_ _ decrease" (Expand Search), "_ f_ decrease" (Expand Search), "_ f_ decreased" (Expand Search), "_ f_ decreases" (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 nm decrease\"))) OR (((\"_ e decrease\") OR (\"_ fe decrease\"))))~".
• Removing quotes may allow a broader search: (((( 50 ms decrease ) OR ( 5 nm decrease ))) OR ((( _ e decrease ) OR ( _ fe decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("50 ms decrease") OR ("5 nm decrease"))) OR ((("_ e decrease") OR ("_ fe decrease"))))*.
