Perhaps you should try some spelling variations:
"coder coding _ algorithms complexity" » "coder coding _ algorithmic complexity" (Expand search), "modern coding _ algorithms complexity" (Expand search), "color coding _ algorithms complexity" (Expand search), "odor coding _ algorithms complexity" (Expand search)
"api with python python programming" » "api with pythons python programming" (Expand search), "api with piton python programming" (Expand search), "api with pitons python programming" (Expand search), "xapi with python python programming" (Expand search), "pi with python python programming" (Expand search), "ai with python python programming" (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 coding _ algorithms complexity\") OR (\"api with python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coding _ algorithms complexity ) OR ( api with python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coding _ algorithms complexity") OR ("api with python python programming"))*.
