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