Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery"
"mat qua dat slippers" » "mat cua dat slippers", "mai qua dat slippers", "sat qua dat slippers", "mat quy dat slippers", "mat qua da slippers", "mat qua dan slippers", "mat qua dat grippers"
"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: "((((\"mat qua dat slippers\") OR (\"python using java slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( mat qua dat slippers ) OR ( python using java slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("mat qua dat slippers") OR ("python using java slippery"))) OR ("locating bug code snippets"))*.
