• Removing quotes may allow a broader search: (((( duong java java snippets ) OR ( dong von code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("duong java java snippets") OR ("dong von code snippets"))) OR ("locating bug code snippets"))*.
