Perhaps you should try some spelling variations:
"tran hoan code snippets" » "tran hoang code snippets", "tuan hoan code snippets", "tran doan code snippets", "tran hoan code slippers"
"dung dung code snippets" » "duong dung code snippets", "ung dung code snippets", "dung ung code snippets", "dung dung cong snippets", "dung dung co snippets", "dung dung de snippets", "dung dung 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: "((((\"tran hoan code snippets\") OR (\"dung dung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tran hoan code snippets ) OR ( dung dung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tran hoan code snippets") OR ("dung dung code snippets"))) OR ("locating bug code snippets"))*.
