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