Perhaps you should try some spelling variations:
"dung datat code snippets" » "dung dat code snippets"
"dung vat core snippets" » "dung va core snippets", "dong vat core snippets", "dung dat core snippets", "dung vat co snippets", "dung vat con 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 vat core snippets\") OR (\"dung datat code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung vat core snippets ) OR ( dung datat code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung vat core snippets") OR ("dung datat code snippets"))) OR ("locating bug code snippets"))*.
