Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dat hoi dan snippets" » "dat thoi dan snippets", "dai hoi dan snippets", "dan hoi dan snippets", "dat hoa dan snippets", "dat hoc dan snippets", "dat hoi dap snippets", "dat hoi 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 hoi dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dat hoi dan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dat hoi dan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
