Perhaps you should try some spelling variations:
"coder functions optimum complexity from" » "coder functions medium complexity from" (Expand search), "coder functions time complexity from" (Expand search), "coder functions exptime complexity from" (Expand search), "coder functions maximum complexity from" (Expand search), "coder function maximum complexity from" (Expand search), "power functions optimum complexity from" (Expand search), "order functions optimum complexity from" (Expand search), "colour functions optimum complexity from" (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 functions optimum complexity from\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder functions optimum complexity from ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder functions optimum complexity from") OR ("api python python python programming"))*.
