Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"vi sung a slippery" » "vi ung a slippery", "vi dung a slippery", "van sung a slippery", "vi sung nam slippery", "vi sung cua slippery", "vi sung hai slippery", "vi sung 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 sung a slippery\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( vi sung a slippery ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi sung a slippery") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
