Perhaps you should try some spelling variations:
"coder string mining algorithms complexity" » "coder string mining algorithmic complexity" (Expand search), "coder string learning algorithms complexity" (Expand search), "coder string routing algorithms complexity" (Expand search), "coder string winding algorithms complexity" (Expand search), "coder strip mining algorithms complexity" (Expand search), "coder during mining algorithms complexity" (Expand search), "cordel string mining algorithms complexity" (Expand search), "closed string mining algorithms complexity" (Expand search), "modelo string mining algorithms complexity" (Expand search)
"api in python python programming" » "api in pythons python programming" (Expand search), "api in piton python programming" (Expand search), "api in pitons python programming" (Expand search), "api _ python python programming" (Expand search), "api an python python programming" (Expand search), "fpi in python python programming" (Expand search), "gpi in 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 mining algorithms complexity") OR ("api in python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder string mining algorithms complexity\") OR (\"api in python python programming\"))".
• Removing quotes may allow a broader search: (( coder string mining algorithms complexity ) OR ( api in python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder string mining algorithms complexity") OR ("api in python python programming"))*.
