Which languages are supported?

[dejudicibus]

Which languages are supported? I would like to know if Italian is supported too and, in case it is not, how can I contribute to its support. Thank you in advance.

The UI is effectively the PHP UI of the Solr Core.
Italian is already localized, if you don't have it, you may activate it over "Configuration"
http://yourserver/search-apps/setup/
Search user interface > select Italian

If you want to modify or add new languages, go to the sub-project solr-php-ui
src/config/config.i18n.php
https://github.com/opensemanticsearch/solr-php-ui/blob/master/src/config/config.i18n.php

and add your texts in Arrays.
Try everything first on your own installation (locally will be at: /etc/solr-php-ui/config.i18n.php), make sure to follow correct PHP syntax and then later you can add it online.
