Perhaps you should try some spelling variations:
"advanced computational using computer program" » "and computational using computer program" (Expand search), "based computational using computer program" (Expand search), "advanced computation using computer program" (Expand search), "advanced computations using computer program" (Expand search), "advanced computacional usinas computer program" (Expand search)
"using file system python programming" » "using file systems python programming" (Expand search), "using file sistemas python programming" (Expand search), "using file pytm python programming" (Expand search), "using five system python programming" (Expand search), "using fine system python programming" (Expand search), "using fire system 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 using computer program\") OR (\"using file system python programming\"))~".
• Removing quotes may allow a broader search: (( advanced computational using computer program ) OR ( using file system python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced computational using computer program") OR ("using file system python programming"))*.
