Perhaps you should try some spelling variations:
"coder _ programming algorithm complexity" » "coder _ processing algorithm complexity" (Expand search), "coder _ programming algorithms complexity" (Expand search), "coder _ programming algorithmic complexity" (Expand search), "coder _ programming algorithm context" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder _ programming algorithm complexity") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder _ programming algorithm complexity\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder _ programming algorithm complexity ) OR ( api python python python programming ))*.
