Perhaps you should try some spelling variations:
"using real java snippets" » "using metal java snippets", "using raw java snippets"
"vi luong che snippets" » "vi luong cho snippets", "vi luong chu snippets", "vi duong che snippets", "dai luong che snippets", "van luong che snippets", "hai luong che snippets"
"locating bug code snippets" » "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 luong che snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using real java snippets ) OR ( vi luong che snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using real java snippets") OR ("vi luong che snippets"))) OR ("locating bug code snippets"))*.
