Perhaps you should try some spelling variations:
decrease disease » decreases disease (Expand search), increase disease (Expand search), increased disease (Expand search)
disease progress » disease process (Expand search), disease progression (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (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 and » python based (Expand search)
and python » in python (Expand search), on python (Expand search), api python (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 disease progress ) OR ( python AND python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease disease progress ) OR ( python and python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease disease progress ) OR ( python and python python programming ))*.
