Perhaps you should try some spelling variations:
"using lc code snippets" » "using c code snippets", "using l code snippets", "using low code snippets", "using lbm code snippets", "using lc code slippers"
"dung dan tran snippets" » "dung dat tran snippets", "dung san tran snippets", "tung dan tran snippets", "dung dang tran snippets", "dung tan tran snippets", "dung dan than snippets", "dung dan tran 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 lc code snippets\") OR (\"dung dan tran snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using lc code snippets ) OR ( dung dan tran snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using lc code snippets") OR ("dung dan tran snippets"))) OR ("locating bug code snippets"))*.
