Perhaps you should try some spelling variations:
"using data java grippers" » "using java java grippers", "using sat java grippers", "missing data java grippers", "using data java slippers"
"vi using c snippets" » "vi sinh c snippets", "_ using c snippets", "vi ung c snippets", "vi using lc snippets", "vi using a snippets", "vi using _ snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

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: "((((\"vi using c snippets\") OR (\"using data java grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi using c snippets ) OR ( using data java grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi using c snippets") OR ("using data java grippers"))) OR ("locating bug code snippets"))*.
