Perhaps you should try some spelling variations:
"dung cho code snippets" » "dung cho cong snippets", "dung cfd code snippets", "dung cho con snippets", "dung cho code slippers"
"chan doan code snippets" » "phan doan code snippets", "can doan code snippets", "nhan doan code snippets", "chan doanh code snippets", "chan dan code snippets", "chan toan code snippets", "chan doan 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: "((((\"chan doan code snippets\") OR (\"dung cho code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( chan doan code snippets ) OR ( dung cho code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("chan doan code snippets") OR ("dung cho code snippets"))) OR ("locating bug code snippets"))*.
