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