Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"locating bug core snippets" » "locating bug code snippets"
"dong va code snippets" » "dung va code snippets", "dong ha code snippets", "luong va code snippets"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("python using raw snippets") OR ("dong va code snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( python using raw snippets ) or ( dong va code snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") or ("dong va code snippets"))) or ("locating bug core snippets"))*.
