Perhaps you should try some spelling variations:
"vi using ibm slippers" » "vi using rbf slippers", "vi sinh ibm slippers", "_ using ibm slippers", "vi ung ibm slippers", "vi using ibm slippery", "vi using ibm 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using a java snippets\") OR (\"vi using ibm slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using a java snippets ) OR ( vi using ibm slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using a java snippets") OR ("vi using ibm slippers"))) OR ("locating bug code snippets"))*.
