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