What you are describing is precisely why I never use the mode where Solr
automatically adds unknown fields.
If the field does not exist in the schema before you index the document,
then the best Solr can do is precisely what is configured in the update
processor that adds unknown fields. You can adjust that config, but it
will always be a general purpose guess.
What is actually needed for multiple unknown fields is often outside
what that update processor is capable of detecting and configuring
automatically. For that reason, I set up the schema manually, and I
want indexing to fail if the input documents contain fields that I
haven't defined. Then whoever is doing the indexing can contact me with
their error details, and I can add new fields with the exact required
definition.
Thanks,
