Perhaps you should try some spelling variations:
"dung danh data snippets" » "dung danh bat snippets", "dung dinh dat snippets", "dung dan dat snippets", "dung doanh data snippets", "dung dan data snippets", "dung dang data snippets", "dung danh data slippers"
"dung va code snippets" » "dung va core snippets", "dung va code slippers"
"locating bug code snippets" » "locating bug core snippets", "locating bug code slippers", "locating bung code snippets", "locating bugs 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 va code snippets\") OR (\"dung danh data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung va code snippets ) OR ( dung danh data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung va code snippets") OR ("dung danh data snippets"))) OR ("locating bug code snippets"))*.
