Perhaps you should try some spelling variations:
"thoan tran code snippets" » "hoan tran code snippets", "toan tran code snippets", "tan tran code snippets", "thoan tran cong snippets", "thoan tran code slippers"
"dong dat code snippets" » "dong vat code snippets", "dung dat code snippets", "dong ha code snippets", "dong rate code snippets", "dong dat de snippets", "dong dat 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: "((((\"thoan tran code snippets\") OR (\"dong dat code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thoan tran code snippets ) OR ( dong dat code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thoan tran code snippets") OR ("dong dat code snippets"))) OR ("locating bug code snippets"))*.
