Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"nae va trac snippets" » "nae va tac snippets", "nae tap trac snippets", "name va trac snippets"
"locating bug code slippers" » "locating bung code slippers", "locating bugs code slippers"

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: "((((\"nae va trac snippets\") OR (\"python using code snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( nae va trac snippets ) OR ( python using code snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nae va trac snippets") OR ("python using code snippets"))) OR ("locating bug code slippers"))*.
