Perhaps you should try some spelling variations:
"python using java slippers" » "python using data slippers", "python using java slippery", "python using java grippers"
"dan a code snippets" » "dan ca code snippets", "dan va code snippets", "dan ap code snippets", "dan a core snippets"
"locating bug code snippets" » "locating bug core 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: "((((\"dan a code snippets\") OR (\"python using java slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dan a code snippets ) OR ( python using java slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dan a code snippets") OR ("python using java slippers"))) OR ("locating bug code snippets"))*.
