LGTM. 100 sounds like a good start to me.
Requesting to many docvalue_fields in a search request can potentially be costly because it might incur a per-field per-document seek. This change introduces a soft limit on the number of fields that can be retrieved. The setting can be changed per index using the `index.max_docvalue_fields_search` setting. Relates to elastic#26390

I think 0 is a good minimum value.
