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