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