Perhaps you should try some spelling variations:
"using real java snippets" » "using metal java snippets", "using raw java snippets", "using real java slippers"
"vi cong ty snippets" » "voi cong ty snippets", "va cong ty snippets", "vu cong ty snippets", "vi cong ty slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"using real java snippets\") OR (\"vi cong ty snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using real java snippets ) OR ( vi cong ty snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using real java snippets") OR ("vi cong ty snippets"))) OR ("locating bug code snippets"))*.
