Perhaps you should try some spelling variations:
"coder coder using discrete group" » "coder coder in discrete group" (Expand search), "coder coder using discrete groups" (Expand search), "coder coder using discrete subgroups" (Expand search), "coder decoder using discrete group" (Expand search), "code code using discrete group" (Expand search), "decoder codec using discrete group" (Expand search), "coder coders using discrete group" (Expand search), "coder cover using discrete group" (Expand search), "coder code using discrete group" (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 coder using discrete group\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder coder using discrete group ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder coder using discrete group") OR ("api python python python programming"))*.
