By default, if you add your apex domain (http://acme.com , for example) to the domains area of your console, our crawler will crawl all the content it can find on your website, including content in different languages, whether that content is stored in a sub directory such as a www.acme.com/fnfr/ or on a subdomain such as fnfr.acme.com.
The directory and domain information are stored in the schema fields dir1, dir2 and domain. For example the dir1for www.acme.com/enfr/ would be ‘fn‘fr' (for French) and the domain for enfr.acme.com would be ‘fr.acme.com’. We can then use this information to create search filters, settings and UIs based on different languages.
