Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung java java snippets" » "dung va java snippets"
"trong san phan snippets" » "trong cac phan snippets", "cong san phan snippets", "dong san phan snippets", "trong san pham snippets", "trong van phan snippets", "trong sat phan 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 snippets\") OR (\"trong san phan snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung java java snippets ) OR ( trong san phan snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung java java snippets") OR ("trong san phan snippets"))) OR ("locating bug core snippets"))*.
