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