Perhaps you should try some spelling variations:
and progressions » and progression (Expand search), and regressions (Expand search), and professions (Expand search)
python codigo » python coding (Expand search), python code (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
decrease of » decrease in (Expand search)
of diseases » of disease (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 of diseases AND progressions ) OR ( python codigo python python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of diseases and progressions ) OR ( python codigo python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of diseases and progressions ) OR ( python codigo python python programming ))*.
