Perhaps you should try some spelling variations:
"coder codon usage efficient computation" » "coder codon usage efficiency computation" (Expand search), "coder codon use efficient computation" (Expand search), "coder codon humane efficient computation" (Expand search), "poder codon usage efficient computation" (Expand search), "codes codon usage efficient computation" (Expand search), "coded codon usage efficient computation" (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 codon usage efficient computation\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder codon usage efficient computation ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder codon usage efficient computation") OR ("api python python python programming"))*.
