Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"vi using data grippers" » "vi using java grippers", "vi using sat grippers", "vi missing data grippers", "vi sinh data grippers", "_ using data grippers", "vi ung data grippers", "vi using data slippers"
"using a java snippets" » "using _ java 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: "((((\"using a java snippets\") OR (\"vi using data grippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using a java snippets ) OR ( vi using data grippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using a java snippets") OR ("vi using data grippers"))) OR ("locating bug core snippets"))*.
