Similar Result Collapsed

(from github.com/dvlop)
I talk about fees 12.4 version.

When I turn on the “Similar Result Collapsed” option, as a result of the search, I see only one answer.

This does not group result by domain name.

Similar Result Collapsed groups results by content, not domain.

Content is title & description or only description?
Maybe i have option configure “Similar Result Collapsed” per site ?

(from github.com/marevol)
Content means content field.
This option is for an entire index.

I always see a single result, when I activate the “Similar Result Collapsed” option. Perhaps, it is due to my misconfiguration.
