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