Perhaps you should try some spelling variations:
"codigo javascript python computational program" » "codigo javascript method computational program" (Expand search), "codigo javascript methods computational program" (Expand search), "codigo javascript on computational program" (Expand search), "codigo script python computational program" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ 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: "((\"codigo javascript python computational program\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( codigo javascript python computational program ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("codigo javascript python computational program") OR ("using in python python programming"))*.
