Documentation about pagination

[omgslinux]

I'm trying to use ux-live component on a search form, regardless there's an entity attached to the form class. I've tried to follow the documentation and the trait, etc, and I get the first page, but I'm unable to have the next page, because the search values are lost (and the object is null) when querying for the next page. I'm not using knp paginator, but I guess live components should take care of the situation.

Regardless I might be wrong or coded unproperly, I think the best way would be to add some documentation about search forms and how to manage the situation.

I found recently #1509 and #2553 about another issue that took me some headaches and I'm not sure if it could be the same situation.

Thanks in advance.
