Perhaps you should try some spelling variations:
"dung data code snippets" » "dung dat code snippets", "dung dan code snippets", "dung dau code snippets", "dung rate code snippets"
"dung phan mo snippets" » "dung nhan mo snippets", "dung luan mo snippets", "dung ha mo snippets", "dung phap mo snippets", "dung phan bo snippets", "dung phan co 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: "((((\"dung data code snippets\") OR (\"dung phan mo snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung data code snippets ) OR ( dung phan mo snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung data code snippets") OR ("dung phan mo snippets"))) OR ("locating bug code snippets"))*.
