Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java java slippery" » "using data java slippery", "using java java slippers"
"vi using a snippets" » "vi sinh a snippets", "_ using a snippets", "vi ung a snippets", "vi using a slippers"

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