Perhaps you should try some spelling variations:
"cnnhung cfd code snippets" » "cnnhung cfd core snippets", "cnnhung cfd code slippers", "cnnhuong cfd code snippets", "cnnnhung cfd code snippets", "cnnchung cfd code snippets"
"hung v code snippets" » "hung v core snippets", "hung v code slippers", "huong v code snippets", "nhung v code snippets", "chung v code snippets"
"locating bug code snippets" » "locating bug core 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: "((((\"cnnhung cfd code snippets\") OR (\"hung v code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cnnhung cfd code snippets ) OR ( hung v code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cnnhung cfd code snippets") OR ("hung v code snippets"))) OR ("locating bug code snippets"))*.
