Perhaps you should try some spelling variations:
methodological problems » methodological process (Expand search), methodological profile (Expand search), methodological proposals (Expand search)
clustering pattern » cluster pattern (Expand search), flowering pattern (Expand search), cluster patterns (Expand search)
in methodological » on methodological (Expand search), and methodological (Expand search), _ methodological (Expand search)

pattern python » pattern action (Expand search), pattern method (Expand search)
coder notion » coder solution (Expand search)

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

• Removing quotes may allow a broader search: (( coder notion in methodological problems ) OR ( using clustering pattern python programming ))~.
