Perhaps you should try some spelling variations:
"coder decoding _ algorithm complexity" » "coder decoding _ algorithms complexity" (Expand search), "coder decoding _ algorithmic complexity" (Expand search), "coding decoding _ algorithm complexity" (Expand search), "coder decoder _ algorithm complexity" (Expand search), "barcode decoding _ algorithm 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder decoding _ algorithm complexity\") OR (\"api in python python programming\"))~".
• Removing quotes may allow a broader search: (( coder decoding _ algorithm complexity ) OR ( api in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder decoding _ algorithm complexity") OR ("api in python python programming"))*.
