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 may cd snippets" » "dung va cd snippets", "dung tai cd snippets", "mang may cd 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 may cd snippets\") OR (\"dung data code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung may cd snippets ) OR ( dung data code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung may cd snippets") OR ("dung data code snippets"))) OR ("locating bugs code snippets"))*.
