Perhaps you should try some spelling variations:
"coder coder decoder and complexity" » "coder encoder decoder and complexity" (Expand search), "code code decoder and complexity" (Expand search), "decoder codec decoder and complexity" (Expand search), "codesc poder decoder and complexity" (Expand search), "coder coder decode and complexity" (Expand search), "coder coder encoder and complexity" (Expand search), "coder coder decoder in complexity" (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 decoder and complexity\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder decoder and complexity ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder decoder and complexity") OR ("api python python python programming"))*.
