Perhaps you should try some spelling variations:
"coder coder using variational method" » "coder coder using variational methods" (Expand search), "coder coder using vibrational method" (Expand search), "coder coder using fractional method" (Expand search), "coder coder using traditional method" (Expand search), "coder decoder using variational method" (Expand search), "code code using variational method" (Expand search), "decoder codec using variational method" (Expand search), "coder coders using variational method" (Expand search), "coder cover using variational method" (Expand search), "coder code using variational method" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python 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 coder using variational method\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder using variational method ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder using variational method") OR ("api python python python programming"))*.
