Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"nang van java snippets" » "dang van java snippets", "tang van java snippets", "lang van java snippets", "nang van java slippers"
"using a java snippets" » "using _ java snippets", "using a java 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: "((((\"nang van java snippets\") OR (\"using a java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( nang van java snippets ) OR ( using a java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nang van java snippets") OR ("using a java snippets"))) OR ("locating bugs code snippets"))*.
