• Removing quotes may allow a broader search: (((( dung viiiian code snippets ) OR ( dung v code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung viiiian code snippets") OR ("dung v code snippets"))) OR ("locating bug code snippets"))*.
