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