Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using lc code snippets" » "using c code snippets", "using l code snippets", "using low code snippets", "using lbm code snippets"
"dung dat toc snippets" » "dung va toc snippets", "dung tai toc snippets", "dung dan toc snippets", "dung dat doc snippets", "dung dat nuoc 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 lc code snippets\") OR (\"dung dat toc snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using lc code snippets ) OR ( dung dat toc snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using lc code snippets") OR ("dung dat toc snippets"))) OR ("locating bugs code snippets"))*.
