Perhaps you should try some spelling variations:
"dang hung code snippets" » "dang quang code snippets", "manh hung code snippets", "dang cong code snippets", "dang hung code slippers"
"trinh va code snippets" » "trinh van code snippets", "trinh vat code snippets", "trinh ve code snippets", "trinh va 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 va code snippets\") OR (\"dang hung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh va code snippets ) OR ( dang hung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh va code snippets") OR ("dang hung code snippets"))) OR ("locating bug code snippets"))*.
