Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dung java java snippets" » "dung va java snippets"
"tan tran tri snippets" » "tan trang tri snippets", "tan tran thi snippets", "tan trang trai snippets", "toan tran tri snippets", "than tran tri snippets", "tuan tran tri 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: "((((\"tan tran tri snippets\") OR (\"dung java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( tan tran tri snippets ) OR ( dung java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tan tran tri snippets") OR ("dung java java snippets"))) OR ("locating bug core snippets"))*.
