Perhaps you should try some spelling variations:
"a non decrease" » "_ non decrease" (Expand Search), "a non decreased" (Expand Search), "a non increase" (Expand Search)
"5 nn decrease" » "k nn decrease" (Expand Search), "_ nn decrease" (Expand Search), "5 nn decreased" (Expand Search), "5 nn increase" (Expand Search)
"3d point decrease" » "3d point decreased" (Expand Search), "3d point increase" (Expand Search)
"5 nm decrease" » "5 nm decreased" (Expand Search), "5 nm increase" (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: (("5 nn decrease") OR ((((("3d point decrease") OR ("a non decrease"))) OR ("5 nm decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"5 nn decrease\") OR (((((\"3d point decrease\") OR (\"a non decrease\"))) OR (\"5 nm decrease\"))))*".
• Removing quotes may allow a broader search: (( 5 nn decrease ) OR ((((( 3d point decrease ) OR ( a non decrease ))) OR ( 5 nm decrease ))))*.
