Perhaps you should try some spelling variations:
"and compositional data computational program" » "and compositional and computational program" (Expand search), "and compositional via computational program" (Expand search), "and compositional based computational program" (Expand search), "and composition data computational program" (Expand search), "and computational data computational program" (Expand search), "acid composition data computational program" (Expand search)
"using coding in python programming" » "using coping in python programming" (Expand search), "using coating in python programming" (Expand search), "using cooking in python programming" (Expand search), "using coding rna python programming" (Expand search), "using coding and python programming" (Expand search), "using coding _ python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("and compositional data computational program") OR ("using coding in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and compositional data computational program\") OR (\"using coding in python programming\"))".
• Removing quotes may allow a broader search: (( and compositional data computational program ) OR ( using coding in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and compositional data computational program") OR ("using coding in python programming"))*.
