Perhaps you should try some spelling variations:
"advance computational and computer program" » "advanced computational and computer program" (Expand search), "advancing computational and computer program" (Expand search), "advanced computations and computer program" (Expand search), "advance computational fluid computer program" (Expand search), "advance computational _ computer program" (Expand search)
"using coding opencv python programming" » "using using opencv python programming" (Expand search), "using codigo opencl python programming" (Expand search), "using coding pnc python programming" (Expand search), "using coping opencv python programming" (Expand search), "using coating opencv python programming" (Expand search), "using cooking 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: "((\"advance computational and computer program\") OR (\"using coding opencv python programming\"))~".
• Removing quotes may allow a broader search: (( advance computational and computer program ) OR ( using coding opencv python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advance computational and computer program") OR ("using coding opencv python programming"))*.
