Perhaps you should try some spelling variations:
"50 μ decrease" » "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search), "50 a decreased" (Expand Search), "10 μ decrease" (Expand Search), "5 μ decrease" (Expand Search)
"10 we decrease" » "10 nn decrease" (Expand Search), "10 mean decrease" (Expand Search), "10 teer decrease" (Expand Search), "1_ we decrease" (Expand Search), "10 re decrease" (Expand Search), "16 we decrease" (Expand Search)
"50 a decrease" » "50 _ decreased" (Expand Search), "50 _ decreases" (Expand Search), "50 c decrease" (Expand Search), "5 a decrease" (Expand Search), "0 a decrease" (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 a decrease\") OR (\"50 μ decrease\"))) OR (((\"50 _ decrease\") OR (\"10 we decrease\"))))~".
• Removing quotes may allow a broader search: (((( 50 a decrease ) OR ( 50 μ decrease ))) OR ((( 50 _ decrease ) OR ( 10 we decrease ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("50 a decrease") OR ("50 μ decrease"))) OR ((("50 _ decrease") OR ("10 we decrease"))))*.
