Perhaps you should try some spelling variations:
"a a decrease" » "a al decrease" (Expand Search), "a la decrease" (Expand Search), "a a decreased" (Expand Search), "a a increase" (Expand Search)
"50 ms decrease" » "50 ms decreased" (Expand Search), "50 ms increase" (Expand Search)
"_ e decrease" » "_ e decreased" (Expand Search), "_ e increase" (Expand Search)
"_ finite decrease" » "_ finite decreased" (Expand Search), "_ finite increase" (Expand Search)

Try widening your search to All Fields.

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 ((((("_ e decrease") OR ("_ finite decrease"))) OR ("a a decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"50 ms decrease\") OR (((((\"_ e decrease\") OR (\"_ finite decrease\"))) OR (\"a a decrease\"))))".
• Removing quotes may allow a broader search: (( 50 ms decrease ) OR ((((( _ e decrease ) OR ( _ finite decrease ))) OR ( a a decrease )))).
• Adding a wildcard symbol may retrieve word variants: (("50 ms decrease") OR ((((("_ e decrease") OR ("_ finite decrease"))) OR ("a a decrease"))))*.
