Perhaps you should try some spelling variations:
"dang using java snippets" » "dang sinh java snippets", "data using java snippets", "dang ung java snippets", "dang using data snippets", "dang using java slippers"
"dung von code snippets" » "dong von code snippets", "dung cong code snippets", "dung va code snippets", "dung von cong snippets", "dung von code slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"dang using java snippets\") OR (\"dung von code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dang using java snippets ) OR ( dung von code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dang using java snippets") OR ("dung von code snippets"))) OR ("locating bug code snippets"))*.
