Perhaps you should try some spelling variations:
"using computational using declarative programming" » "using computational using reactive programming" (Expand search), "and computational using declarative programming" (Expand search), "using computation using declarative programming" (Expand search), "using computations using declarative programming" (Expand search), "using computacional usinas declarative programming" (Expand search), "using computational mining declarative programming" (Expand search), "using computational in declarative programming" (Expand search), "using computational engine declarative programming" (Expand search)
"using code from python programming" » "using code from pathogen programming" (Expand search), "using code from anthony programming" (Expand search), "using cone from python programming" (Expand search), "using co from python programming" (Expand search), "using co2 from python programming" (Expand search), "using code form 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: "((\"using computational using declarative programming\") OR (\"using code from python programming\"))~".
• Removing quotes may allow a broader search: (( using computational using declarative programming ) OR ( using code from python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational using declarative programming") OR ("using code from python programming"))*.
