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