Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"tri thi dan snippets" » "tri tai dan snippets", "tai thi dan snippets", "thi thi dan snippets", "tri thi doan snippets", "tri thi lan snippets", "tri thi dai snippets", "tri thi dan slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 ("tri thi dan snippets"))) OR ("locating bug code snippets"))~.
• Removing quotes may allow a broader search: (((( python using raw snippets ) or ( tri thi dan snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") or ("tri thi dan snippets"))) or ("locating bug code snippets"))*.
