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