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