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

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