Perhaps you should try some spelling variations:
"coder coding and algorithms doi" » "coder coding and algorithm doi" (Expand search), "coder coding and algorithms on" (Expand search), "coder coding and algorithms of" (Expand search), "modern coding and algorithms doi" (Expand search), "color coding and algorithms doi" (Expand search), "odor coding and algorithms doi" (Expand search), "coder coding rna algorithms doi" (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 coding and algorithms doi\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coding and algorithms doi ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coding and algorithms doi") OR ("api python python python programming"))*.
