Perhaps you should try some spelling variations:
"trinh cau ve snippets" » "trinh chat ve snippets", "trinh chao ve snippets", "trinh tu ve snippets", "trinh dau ve snippets", "trinh cuu ve snippets", "trinh ca ve snippets"
"trong cac code snippets" » "trong cac cong snippets", "trong cac co snippets", "trong 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: "((((\"trong cac code snippets\") OR (\"trinh cau ve snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trong cac code snippets ) OR ( trinh cau ve snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trong cac code snippets") OR ("trinh cau ve snippets"))) OR ("locating bug code snippets"))*.
