decrease warming » decrease walking (Expand search), increased warming (Expand search), decrease during (Expand search)
decreases matter » decreases water (Expand search), decreases after (Expand search), decreasing matter (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 AND decrease il decrease ) OR ( decrease warming decreases matter object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease il decrease ) OR ( decrease warming decreases matter object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease il decrease ) OR ( decrease warming decreases matter object ))*.
