Perhaps you should try some spelling variations:
"coding coding and algorithms complexity" » "coding coding and algorithmic complexity" (Expand search), "coding decoding and algorithms complexity" (Expand search), "coding using and algorithms complexity" (Expand search), "coding canine and algorithms complexity" (Expand search), "coding coding rna algorithms 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), "manim 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: "((\"coding coding and algorithms complexity\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coding coding and algorithms complexity ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coding coding and algorithms complexity") OR ("api python python python programming"))*.
