Perhaps you should try some spelling variations:
"dung gian trong snippets" » "duong gian trong snippets", "dung giao trong snippets", "dung giai trong snippets", "dung gian trong slippers"
"using c code snippets" » "using lc code snippets", "using a code snippets", "using _ code snippets", "using cfd code snippets", "using c 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: "((((\"using c code snippets\") OR (\"dung gian trong snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using c code snippets ) OR ( dung gian trong snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using c code snippets") OR ("dung gian trong snippets"))) OR ("locating bug code snippets"))*.
