Perhaps you should try some spelling variations:
"and computational in declarative programming" » "and computational in reactive programming" (Expand search), "_ computational in declarative programming" (Expand search), "and computational and declarative programming" (Expand search), "and computational _ declarative programming" (Expand search), "and computational 3d declarative programming" (Expand search), "and computational on declarative programming" (Expand search), "and computational of declarative programming" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing 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: "((\"and computational in declarative programming\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( and computational in declarative programming ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational in declarative programming") OR ("using using python python programming"))*.
