Perhaps you should try some spelling variations:
"name tap toan snippets" » "nam tai toan snippets", "nam tan toan snippets", "nam tay toan snippets", "name tap doan snippets", "name tap quan snippets", "name bai toan snippets"
"python using a slippery" » "python using a slippers"
"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: "((((\"name tap toan snippets\") OR (\"python using a slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( name tap toan snippets ) OR ( python using a slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("name tap toan snippets") OR ("python using a slippery"))) OR ("locating bug code snippets"))*.
