Perhaps you should try some spelling variations:
"50 ms decrease" » "50 _ decrease" (Expand Search)
"_ fe decrease" » "_ _ decrease" (Expand Search), "_ f_ decrease" (Expand Search), "_ f_ decreased" (Expand Search), "_ f_ decreases" (Expand Search)
"i wt decrease" » "i _ decrease" (Expand Search), "_ wt decrease" (Expand Search), "i et decrease" (Expand Search), "2 wt 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 (((((\"_ e decrease\") OR (\"_ fe decrease\"))) OR (\"i wt decrease\"))))~".
• Removing quotes may allow a broader search: (( 50 ms decrease ) OR ((((( _ e decrease ) OR ( _ fe decrease ))) OR ( i wt decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (("50 ms decrease") OR ((((("_ e decrease") OR ("_ fe decrease"))) OR ("i wt decrease"))))*.
