Perhaps you should try some spelling variations:
"advanced computational java computer program" » "and computational java computer program" (Expand search), "based computational java computer program" (Expand search), "advanced computacional java computer program" (Expand search), "advanced computational data computer program" (Expand search), "advanced computational and computer program" (Expand search)
"using using opencv python programming" » "using using opencl python programming" (Expand search), "using using open python programming" (Expand search), "using usando opencv python programming" (Expand search), "using fusing opencv python programming" (Expand search), "housing using opencv python programming" (Expand search), "nursing using opencv 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: "((\"advanced computational java computer program\") OR (\"using using opencv python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computational java computer program ) OR ( using using opencv python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational java computer program") OR ("using using opencv python programming"))*.
