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