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