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