Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung veeaaan code snippets" » "dung vaeeaaan code snippets", "dung vieeaaan code snippets", "dung veeeaaan code snippets"
"dung v code snippets" » "dung va code snippets", "dung vi code snippets", "dung ve 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: "((((\"dung veeaaan code snippets\") OR (\"dung v code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung veeaaan code snippets ) OR ( dung v code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung veeaaan code snippets") OR ("dung v code snippets"))) OR ("locating bug core snippets"))*.
