Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"tao danh su snippets" » "cao danh su snippets", "tac danh su snippets", "tao anh su snippets", "tao dang su snippets", "tao dan su snippets", "tao danh tu snippets", "tao danh 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: "((((\"tao danh su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tao danh su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tao danh su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
