Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"vi using raw grippers" » "vi using real grippers", "vi using a grippers", "vi using low grippers", "vi sinh raw grippers", "_ using raw grippers", "vi ung raw grippers", "vi using raw slippers"

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