Perhaps you should try some spelling variations:
case complexity » the complexity (Expand search), and complexity (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
line python » lines python (Expand search), online python (Expand search), in python (Expand search)
poder case » poder crise (Expand search), poder bases (Expand search), poder casos (Expand search)
using line » using life (Expand search), using linear (Expand search), using online (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( poder case complexity control program ) OR ( using line python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( poder case complexity control program ) OR ( using line python python programming ))*.
