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