Perhaps you should try some spelling variations:
"tan tran code snippets" » "tan tran cong snippets", "toan tran code snippets", "than tran code snippets", "tuan tran code snippets", "tan tran code slippers"
"dong cho code snippets" » "dung cho code snippets", "dong co code snippets", "dong hoc code snippets", "dong cho cong snippets", "dong cfd code snippets", "dong cho con snippets", "dong cho 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: "((((\"tan tran code snippets\") OR (\"dong cho code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tan tran code snippets ) OR ( dong cho code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tan tran code snippets") OR ("dong cho code snippets"))) OR ("locating bug code snippets"))*.
