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