• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( vi trong dan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("vi trong dan snippets"))) OR ("locating bugs code snippets"))*.
