Perhaps you should try some spelling variations:
"based computational on compositional data" » "and computational on compositional data" (Expand search), "by computational on compositional data" (Expand search), "based computational one compositional data" (Expand search), "based computacional on compositional data" (Expand search), "based computational and compositional data" (Expand search), "based computational of compositional data" (Expand search), "based computational _ compositional data" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: "((\"based computational on compositional data\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( based computational on compositional data ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computational on compositional data") OR ("using coding python python programming"))*.
