Perhaps you should try some spelling variations:
"trinh cau cho snippets" » "trinh chat cho snippets", "trinh chao cho snippets", "trinh tu cho snippets", "trinh cap cho snippets", "trinh cao cho snippets", "trinh cu cho snippets"
"dung cac code snippets" » "luong cac code snippets", "dung cho code snippets", "dung tai code snippets", "dung cac cong snippets", "dung cac co snippets", "dung cac che snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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 cac code snippets\") OR (\"trinh cau cho snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung cac code snippets ) OR ( trinh cau cho snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung cac code snippets") OR ("trinh cau cho snippets"))) OR ("locating bug code snippets"))*.
