Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung java java slippery" » "dung va java slippery", "dung java java slippers"
"trong dat thuc snippets" » "trong dam thuc snippets", "trong dan thuc snippets", "trong dao thuc snippets", "trong sat thuc snippets", "trong dat thu 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: "((((\"dung java java slippery\") OR (\"trong dat thuc snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung java java slippery ) OR ( trong dat thuc snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung java java slippery") OR ("trong dat thuc snippets"))) OR ("locating bug core snippets"))*.
