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