Perhaps you should try some spelling variations:
"trong cong code snippets" » "trong cong cong snippets", "trong cong co snippets", "trong cong che snippets", "trong cong code slippers"
"dung va code snippets" » "dung va 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: "((((\"trong cong code snippets\") OR (\"dung va code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trong cong code snippets ) OR ( dung va code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trong cong code snippets") OR ("dung va code snippets"))) OR ("locating bug code snippets"))*.
