Perhaps you should try some spelling variations:
decreased not » decreased to (Expand search), decreased akt (Expand search), decreased ut (Expand search)
in decreased » is decreased (Expand search), in deceased (Expand search), and decreased (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease can » decrease and (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » can increase (Expand search), and decrease (Expand search), to decrease (Expand search)
decrease 50 » decrease 30 (Expand search), decrease of (Expand search), decrease _ (Expand search)
50 objects » _ objects (Expand search), 3d objects (Expand search), in objects (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease in decreased NOT decrease ) OR ( decrease can decrease 50 objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decreased not decrease ) OR ( decrease can decrease 50 objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decreased not decrease ) OR ( decrease can decrease 50 objects ))*.
