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"
"dung thi phi snippets" » "dung tai phi snippets", "dung tri phi snippets", "dung chi phi snippets", "dung phi phi snippets", "dung thi phu snippets", "dung thi phi 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 (\"dung thi phi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using cfd code snippets ) OR ( dung thi phi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using cfd code snippets") OR ("dung thi phi snippets"))) OR ("locating bugs code snippets"))*.
