Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"danh a dan snippets" » "danh ca dan snippets", "danh va dan snippets", "xanh a dan snippets", "danh ma dan snippets", "danh a dan slippers"

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: "((((\"danh a dan snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( danh a dan snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh a dan snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
