Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"co dan code snippets" » "co dan de snippets", "co ban code snippets", "ca dan code snippets", "cao dang code snippets", "co dan code slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"co dan code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( co dan code snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("co dan code snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
