Perhaps you should try some spelling variations:
"_ test decrease" » "_ west decrease" (Expand Search), "_ test decreased" (Expand Search), "_ test increase" (Expand Search)
"100 nm decrease" » "100 nm decreased" (Expand Search), "100 nm increase" (Expand Search)
"_ text decrease" » "_ text decreased" (Expand Search), "_ text increase" (Expand Search)
"a new decrease" » "a new decreased" (Expand Search), "a new 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: (("100 nm decrease") OR ((((("_ text decrease") OR ("_ test decrease"))) OR ("a new decrease"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"100 nm decrease\") OR (((((\"_ text decrease\") OR (\"_ test decrease\"))) OR (\"a new decrease\"))))*".
• Removing quotes may allow a broader search: (( 100 nm decrease ) OR ((((( _ text decrease ) OR ( _ test decrease ))) OR ( a new decrease ))))*.
