Perhaps you should try some spelling variations:
"and computational java computer program" » "and computacional java computer program" (Expand search), "and computational data computer program" (Expand search), "and computational and computer program" (Expand search), "_ computational java computer program" (Expand search)
"using code form python programming" » "using cone form python programming" (Expand search), "using co form python programming" (Expand search), "using co2 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: "((\"and computational java computer program\") OR (\"using code form python programming\"))*".
• Removing quotes may allow a broader search: (( and computational java computer program ) OR ( using code form python programming ))*.
