Perhaps you should try some spelling variations:
"coder preparation method based program" » "code preparation method based program" (Expand search), "powder preparation method based program" (Expand search), "copper preparation method based program" (Expand search), "coder preparation method and program" (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)

• Removing quotes may allow a broader search: (( coder preparation method based program ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder preparation method based program") OR ("api python python python programming"))*.
