Perhaps you should try some spelling variations:
"dong chung code snippets" » "dong chung co snippets", "dung chung code snippets", "cong chung code snippets", "dong hung code snippets", "dong chung 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 (\"dong chung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh va code snippets ) OR ( dong chung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh va code snippets") OR ("dong chung code snippets"))) OR ("locating bug code snippets"))*.
