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"
"cau giay dan snippets" » "cuu giai dan snippets", "cac giai dan snippets", "cau xay dan snippets", "cau gian dan snippets", "cau giay van snippets", "cau giao dan snippets", "cau giay 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using raw snippets\") OR (\"cau giay dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( cau giay dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("cau giay dan snippets"))) OR ("locating bug code snippets"))*.
