Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search), marked decrease (Expand Search)
laser decrease » larger decrease (Expand Search), linear decrease (Expand Search), water decreases (Expand Search)
_ largest » _ large (Expand Search)
a larger » _ larger (Expand Search), _ large (Expand Search)
a laser » _ laser (Expand Search)
a large » _ large (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: "(( a laser decrease ) OR ((( ((a larger) OR (a large)) decrease ) OR ( _ largest decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( a laser decrease ) OR ((( ((a larger) OR (a large)) decrease ) OR ( _ largest decrease ))))*.
