Perhaps you should try some spelling variations:
"trinh cac code snippets" » "trinh cau code snippets", "trinh chat code snippets", "trinh chao code snippets", "trinh cac cong snippets", "trinh cac co snippets", "trinh cac che snippets", "trinh cac code slippers"
"dang dung code snippets" » "dan dung code snippets", "dang hung code snippets", "dang quang code snippets", "dang dung cong snippets", "dang dung co snippets", "dang dung de snippets", "dang dung code slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"trinh cac code snippets\") OR (\"dang dung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh cac code snippets ) OR ( dang dung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh cac code snippets") OR ("dang dung code snippets"))) OR ("locating bug code snippets"))*.
