Perhaps you should try some spelling variations:
"vi sinh java slippers" » "vi trinh java slippers", "vi using java slippers", "vi sinh va slippers", "vi sinh java slippery", "vi sinh java grippers"
"using a java snippets" » "using _ 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.

• Removing quotes may allow a broader search: (((( vi sinh java slippers ) OR ( using a java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi sinh java slippers") OR ("using a java snippets"))) OR ("locating bug code snippets"))*.
