Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"vung dat doc snippets" » "dung dat doc snippets", "vung va doc snippets", "vung dat duoc snippets", "vung day doc snippets", "vung dat nuoc 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: "((((\"using java code snippets\") OR (\"vung dat doc snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( vung dat doc snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("vung dat doc snippets"))) OR ("locating bugs code snippets"))*.
