Perhaps you should try some spelling variations:
"_ computation using java programming" » "_ computations using java programming" (Expand search), "_ computation in java programming" (Expand search), "_ composition using java programming" (Expand search), "_ computation using and programming" (Expand search), "_ computation using based programming" (Expand search), "_ computation using goal programming" (Expand search)
"usando python python python programming" » "usando pythons python python programming" (Expand search), "usando piton python python programming" (Expand search), "usando pitons 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: "((\"_ computation using java programming\") OR (\"usando python python python programming\"))~".
• Removing quotes may allow a broader search: (( _ computation using java programming ) OR ( usando python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("_ computation using java programming") OR ("usando python python python programming"))*.
