Perhaps you should try some spelling variations:
tone complexity » the complexity (Expand search), code complexity (Expand search), time complexity (Expand search)
samples pythons » samples author's (Expand search)
pythons python » python python (Expand search), pitons python (Expand search), piton python (Expand search)
using samples » using simple (Expand search), using simplex (Expand search), cutting samples (Expand search)
coder » poder (Expand search), codes (Expand search), coded (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: "(( coder tone complexity control program ) OR ( using samples pythons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder tone complexity control program ) OR ( using samples pythons python programming ))*.
