Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"phan van tran snippets" » "pham van tran snippets", "thanh van tran snippets", "luan van tran snippets", "phan van trang snippets", "phan van tranh snippets", "phan van tuan snippets", "phan van tran slippers"
"python using a snippets" » "python using a 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: "((((\"phan van tran snippets\") OR (\"python using a snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( phan van tran snippets ) OR ( python using a snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phan van tran snippets") OR ("python using a snippets"))) OR ("locating bugs code snippets"))*.
