Perhaps you should try some spelling variations:
"coder _ sampling algorithm array" » "coder _ mapping algorithm array" (Expand search), "coder _ matching algorithm array" (Expand search), "coder _ mapping algorithms array" (Expand search), "coder _ sampling algoritmos array" (Expand search), "coder _ sampling algorithm aaa" (Expand search), "coder _ sampling algorithm binary" (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 _ sampling algorithm array\") OR (\"api with python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ sampling algorithm array ) OR ( api with python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ sampling algorithm array") OR ("api with python python programming"))*.
