Perhaps you should try some spelling variations:
"_ using code slippers" » "_ using cfd slippers", "_ using one slippers", "_ housing code slippers"
"using data java slippery" » "using java java slippery", "using sat java slippery", "missing data java slippery"
"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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ using code slippers") OR ("using data java slippery"))) OR ("locating bug code snippets"))~.
• Removing quotes may allow a broader search: (((( _ using code slippers ) or ( using data java slippery ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ using code slippers") or ("using data java slippery"))) or ("locating bug code snippets"))*.
