Perhaps you should try some spelling variations:
"using low noise snippets" » "using low dose snippets"
"dung dan code snippets" » "dung dat code snippets", "dung san code snippets", "tung dan code snippets", "dung dan de 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: "((((\"using low noise snippets\") OR (\"dung dan code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using low noise snippets ) OR ( dung dan code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using low noise snippets") OR ("dung dan code snippets"))) OR ("locating bug code snippets"))*.
