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