Perhaps you should try some spelling variations:
"using real java snippets" » "using metal java snippets", "using raw java snippets"
"_ using data slippers" » "_ using java slippers", "_ using sat slippers", "_ missing data slippers", "_ housing data slippers", "_ using data slippery", "_ using data 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: "((((\"using real java snippets\") OR (\"_ using data slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using real java snippets ) OR ( _ using data slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using real java snippets") OR ("_ using data slippers"))) OR ("locating bug code snippets"))*.
