Perhaps you should try some spelling variations:
"coder code using graph partitioning" » "coder code using and partitioning" (Expand search), "code code using graph partitioning" (Expand search), "modern code using graph partitioning" (Expand search), "color code using graph partitioning" (Expand search), "coder made using graph partitioning" (Expand search), "coder coding using graph partitioning" (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 code using graph partitioning\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder code using graph partitioning ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder code using graph partitioning") OR ("api python python python programming"))*.
