Perhaps you should try some spelling variations:
"coder _ efficient algorithm array" » "coder _ efficient algoritmos array" (Expand search), "coder _ efficient algorithm aaa" (Expand search), "coder _ efficient algorithm binary" (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 _ efficient algorithm array\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder _ efficient algorithm array ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder _ efficient algorithm array") OR ("api python python python programming"))*.
