Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using raw java slippery" » "using real java slippery", "using a java slippery", "using low java slippery", "using raw java slippers"
"dung tai java snippets" » "dung tai va snippets", "dung tai java 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: "((((\"dung tai java snippets\") OR (\"using raw java slippery\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung tai java snippets ) OR ( using raw java slippery ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung tai java snippets") OR ("using raw java slippery"))) OR ("locating bugs code snippets"))*.
