Perhaps you should try some spelling variations:
"coder coder using linear complexity" » "coder coder using lower complexity" (Expand search), "coder coder using higher complexity" (Expand search), "coder decoder using linear complexity" (Expand search), "code code using linear complexity" (Expand search), "decoder codec using linear complexity" (Expand search), "coder coders using linear complexity" (Expand search), "coder cover using linear complexity" (Expand search), "coder code using linear complexity" (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 coder using linear complexity") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder coder using linear complexity\") OR (\"api python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder coder using linear complexity ) OR ( api python python python programming ))*.
