Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"dung truan doi snippets" » "dung truong doi snippets", "dung luan doi snippets", "dung trung doi snippets", "dung truyen doi snippets", "dung quan doi snippets", "dung khuan doi snippets"
"using 3d code snippets" » "using 3 code snippets", "using a code snippets", "using _ code snippets", "using cfd 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 3d code snippets\") OR (\"dung truan doi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using 3d code snippets ) OR ( dung truan doi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using 3d code snippets") OR ("dung truan doi snippets"))) OR ("locating bugs code snippets"))*.
