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