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