Perhaps you should try some spelling variations:
"coder encoded strings in problem" » "coder decoder strings in problem" (Expand search), "coder encoded springs in problem" (Expand search), "coder encoded stings in problem" (Expand search), "coder encoded settings in problem" (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 encoded strings in problem\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder encoded strings in problem ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder encoded strings in problem") OR ("api python python python programming"))*.
