Perhaps you should try some spelling variations:
"python using real snippets" » "python using metal snippets", "python using raw snippets"
"cau doi code snippets" » "cau doi cong snippets", "cau doi co snippets", "cau doi de snippets", "cau hoi code snippets", "cau do code snippets", "cau noi code snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("python using real snippets") OR ("cau doi code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using real snippets\") OR (\"cau doi code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using real snippets ) OR ( cau doi code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using real snippets") OR ("cau doi code snippets"))) OR ("locating bug core snippets"))*.
