Perhaps you should try some spelling variations:
"trinh tu tao snippets" » "trinh ky tao snippets", "trinh do tao snippets", "trinh tu thao snippets", "trinh tuc tao snippets", "trinh tu tai snippets", "trinh tu tao slippers"
"trong cac code snippets" » "trong cac cong snippets", "trong cac co snippets", "trong cac che snippets", "trong cac 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 tu tao snippets\") OR (\"trong cac code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh tu tao snippets ) OR ( trong cac code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh tu tao snippets") OR ("trong cac code snippets"))) OR ("locating bug code snippets"))*.
