Perhaps you should try some spelling variations:
"python using data slippery" » "python using java slippery", "python using sat slippery", "python missing data slippery", "python using data slippers"
"cao de dan snippets" » "nao de dan snippets", "cao de dang snippets", "cao de dao snippets", "cao ke dan snippets", "cao de dan 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: "((((\"cao de dan snippets\") OR (\"python using data slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cao de dan snippets ) OR ( python using data slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cao de dan snippets") OR ("python using data slippery"))) OR ("locating bug code snippets"))*.
