Perhaps you should try some spelling variations:
"dan cuu code snippets" » "dan cuu che snippets", "dan cuu cong snippets", "dan cuu de snippets", "dan cu code snippets", "dan cua code snippets", "dan luu code snippets", "dan cuu code slippers"
"python using a snippets" » "python using a 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: "((((\"dan cuu code snippets\") OR (\"python using a snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dan cuu code snippets ) OR ( python using a snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan cuu code snippets") OR ("python using a snippets"))) OR ("locating bug code snippets"))*.
