Summary:	Solr field cache still uses used a lot of field related RAM
Fix Version:	16.10.6
Fix Version:	17.3.0-rc-1
Description:	Similarly to XWIKI-22820, we noticed that quite a lot of RAM was dedicated to storing data about the field "title_sort" (of type "lowercase"). I notice than in recent version Solr decided to enable docValues by default, and it's now applied to all the types of the default core (except for the "ignored" one). I think we should follow the same logic to avoid keeping having the same problem.

	Actually, it's not possible to enable docValues for "title_sort" becaause it's stored in a "solr.TextField" so there is not much we can do to fix this (unless it's possible to move to a different type, but I don't know).

	Actually, it's not possible to enable docValues for "title_sort" because it's stored in a "solr.TextField" so there is not much we can do to cannot really fix this problem that way (unless it's possible to move to a different type, but I don't know).
