Perhaps you should try some spelling variations:
decrease closure » decrease costs (Expand search)
closure process » disclosure process (Expand search), pressure process (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
python api » python and (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 closure process ) OR ( python api _ python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease closure process ) OR ( python api _ python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease closure process ) OR ( python api _ python programming ))*.
