Perhaps you should try some spelling variations:
"_ feb decrease" » "_ _ decrease" (Expand Search), "_ web decrease" (Expand Search), "_ fed decrease" (Expand Search), "_ fes decrease" (Expand Search), "_ eb decrease" (Expand Search)
"50 ms decrease" » "50 _ decrease" (Expand Search)
"_ fe decrease" » "_ _ decrease" (Expand Search), "_ e decrease" (Expand Search)
"5 wt decrease" » "5 _ decrease" (Expand Search), "_ wt decrease" (Expand Search), "5 ht decrease" (Expand Search), "2 wt decrease" (Expand Search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("50 ms decrease") OR ((((("_ fe decrease") OR ("_ feb decrease"))) OR ("5 wt decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"50 ms decrease\") OR (((((\"_ fe decrease\") OR (\"_ feb decrease\"))) OR (\"5 wt decrease\"))))*".
• Removing quotes may allow a broader search: (( 50 ms decrease ) OR ((((( _ fe decrease ) OR ( _ feb decrease ))) OR ( 5 wt decrease ))))*.
