Perhaps you should try some spelling variations:
"coder string matching algorithms complexity" » "coder string matching algorithmic complexity" (Expand search), "coder string matching algorithm complexity" (Expand search), "coder string mining algorithms complexity" (Expand search), "coder string tracking algorithms complexity" (Expand search), "cordel string matching algorithms complexity" (Expand search), "closed string matching algorithms complexity" (Expand search), "modelo string matching 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.

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