Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"phan anh su snippets" » "pham anh su snippets", "phan thanh su snippets", "phan dang su snippets", "phan hanh su snippets", "phan anh tu snippets", "phan anh so snippets", "phan anh su slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"python using java snippets\") OR (\"phan anh su snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( phan anh su snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("phan anh su snippets"))) OR ("locating bug code snippets"))*.
