Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"cong dong code snippets" » "cong dong co snippets", "cong dong che snippets", "cong dong cong snippets", "cong dong code slippers"
"using c code snippets" » "using lc code snippets", "using a code snippets", "using _ code snippets", "using cfd code snippets", "using c code slippers"

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 (\"cong dong code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using c code snippets ) OR ( cong dong code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using c code snippets") OR ("cong dong code snippets"))) OR ("locating bugs code snippets"))*.
