• Removing quotes may allow a broader search: (((( nhung tri code snippets ) or ( cong cau cong snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhung tri code snippets") or ("cong cau cong snippets"))) or ("locating bug code snippets"))*.
