• Removing quotes may allow a broader search: (((( trong cac code snippets ) or ( trinh mat dan snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trong cac code snippets") or ("trinh mat dan snippets"))) or ("locating bug code snippets"))*.
