Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"dung data code snippets" » "dung dat code snippets", "dung dan code snippets", "dung dau code snippets", "dung rate code snippets"
"dung cho can snippets" » "dung cho cac snippets", "dung cho phan snippets", "dung cho cong 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: "((((\"dung data code snippets\") OR (\"dung cho can snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung data code snippets ) OR ( dung cho can snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung data code snippets") OR ("dung cho can snippets"))) OR ("locating bugs code snippets"))*.
