Perhaps you should try some spelling variations:
"python using data slippery" » "python using java slippery", "python using sat slippery", "python missing data slippery"
"php cu code slippers" » "php cfd code slippers", "pho cu code slippers", "phap cau code slippers", "phap chu code slippers"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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: "((((\"php cu code slippers\") OR (\"python using data slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( php cu code slippers ) OR ( python using data slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("php cu code slippers") OR ("python using data slippery"))) OR ("locating bug code snippets"))*.
