Perhaps you should try some spelling variations:
significantly increase » significantly increased (Expand Search), significant increase (Expand Search), significantly decreased (Expand Search)
increase decrease » increased release (Expand Search), increased crash (Expand Search)
we decrease » _ decrease (Expand Search), nn decrease (Expand Search), mean decrease (Expand Search)
a decrease » _ decrease (Expand Search), _ decreased (Expand Search), _ decreases (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: "\"((\\"significantly ((we decrease) OR (a decrease))\\") OR (\\"significantly increase decrease\\"))\"".
• Removing quotes may allow a broader search: (( significantly ((we decrease) OR (a decrease)) ) OR ( significantly increase decrease )).
