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