Perhaps you should try some spelling variations:
"python using one snippets" » "python using open snippets", "python using pre snippets", "python using online snippets"
"thi choi dan snippets" » "tro choi dan snippets", "thi hai dan snippets", "thi hoa dan snippets", "thi hoi dan snippets", "thi hoc dan snippets"
"locating bug code snippets" » "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 one snippets\") OR (\"thi choi dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using one snippets ) OR ( thi choi dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using one snippets") OR ("thi choi dan snippets"))) OR ("locating bug code snippets"))*.
