Wrong URL for i18 multisite

[arbinada-com]

When using i18_multisite plugin the generation of search.toml uses wrong URLs.

For example

[[input.files]]
path = "pages/about_fr.html"
url = "/pages/about_fr.html"

should be

[[input.files]]
path = "pages/about_fr.html"
url = "/fr/pages/about_fr.html"

To solve:

• add SEARCH_I18_SUBSITE parameter to generator
• in site configuration add as follows

I18N_SUBSITES = {
    "fr": {
        "SITENAME": "Mon beau site",
        "SEARCH_I18_SUBSITE": "fr"
    }
}
