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"
"dung cfd code snippets" » "dung cho code snippets", "dung cua code snippets", "dung co code snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("using lc code snippets") OR ("dung cfd code snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( using lc code snippets ) or ( dung cfd code snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using lc code snippets") or ("dung cfd code snippets"))) or ("locating bug core snippets"))*.
