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