Perhaps you should try some spelling variations:
"dan dung code snippets" » "dan dung cong snippets", "dan dung co snippets", "dan dung de snippets", "van dung code snippets", "tin dung code snippets", "ap dung code snippets", "dan dung code slippers"
"trinh ve code snippets" » "trinh he code snippets", "trinh va code snippets", "trinh vi code snippets", "trinh ve code slippers"
"locating bug code 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: "((((\"trinh ve code snippets\") OR (\"dan dung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh ve code snippets ) OR ( dan dung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh ve code snippets") OR ("dan dung code snippets"))) OR ("locating bug code snippets"))*.
