Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using cfd code snippets" » "using 3d code snippets", "using c code snippets", "using cfd code slippers"
"anh viet code snippets" » "anh viet co snippets", "anh viet some snippets", "anh viet 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 cfd code snippets\") OR (\"anh viet code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using cfd code snippets ) OR ( anh viet code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using cfd code snippets") OR ("anh viet code snippets"))) OR ("locating bugs code snippets"))*.
