Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"dung danh tran snippets" » "dung doanh tran snippets", "dung dan tran snippets", "dung dang tran snippets", "dung canh tranh snippets", "dung hanh trang snippets", "dung danh tran slippers"
"using a code snippets" » "using a code slippers"

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: "((((\"using a code snippets\") OR (\"dung danh tran snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using a code snippets ) OR ( dung danh tran snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using a code snippets") OR ("dung danh tran snippets"))) OR ("locating bugs code snippets"))*.
