Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"dung trinh do snippets" » "dung tinh do snippets", "dong trinh do snippets", "cong trinh do snippets", "dung trinh ky snippets"
"using cfd code snippets" » "using 3d code snippets", "using c 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 cfd code snippets\") OR (\"dung trinh do snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using cfd code snippets ) OR ( dung trinh do snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using cfd code snippets") OR ("dung trinh do snippets"))) OR ("locating bugs code snippets"))*.
