Perhaps you should try some spelling variations:
"dung trong code snippets" » "dung trong cong snippets", "dung trong co snippets", "dung trong che snippets", "dung trong code slippers"
"trinh lap dan snippets" » "trinh luat dan snippets", "trinh luan dan snippets", "trinh phap dan snippets", "trinh lap dat snippets", "trinh lap ban snippets", "trinh hap dan snippets", "trinh lap dan 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 lap dan snippets\") OR (\"dung trong code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh lap dan snippets ) OR ( dung trong code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh lap dan snippets") OR ("dung trong code snippets"))) OR ("locating bug code snippets"))*.
