Perhaps you should try some spelling variations:
"trinh nhac dan snippets" » "trinh nha dan snippets", "trinh nhap dan snippets", "trinh khac dan snippets", "trinh nhan dan snippets", "trinh hoc dan snippets", "trinh cac dan snippets", "trinh nhac dan 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", "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 a snippets\") OR (\"trinh nhac dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( trinh nhac dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("trinh nhac dan snippets"))) OR ("locating bug code snippets"))*.
