Perhaps you should try some spelling variations:
"python using data slippers" » "python using java slippers", "python using sat slippers", "python missing data slippers", "python using data grippers"
"chu le van slippery" » "chu de van slippery", "nhu le van slippery", "chul lee van slippery"
"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: "((((\"python using data slippers\") OR (\"chu le van slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data slippers ) OR ( chu le van slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data slippers") OR ("chu le van slippery"))) OR ("locating bug code snippets"))*.
