Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"nam do su snippets" » "nam dao su snippets", "nam doi su snippets", "nam bo su snippets", "nam do sut snippets", "nam do tu snippets", "nam co su snippets", "nam do 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: "((((\"nam do su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( nam do su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nam do su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
