>
> Schemaless mode does not work if you use DIH to index. This mode being most
> useful for prototyping, it makes sense to be able to use it with DIH, another
> great Solr tool that allows people to index some db content pretty fast.
> I imagine this also affects other sources DIH can handle, not just SQL.
> The issue is DIH code does not add fields it does not know so far, so the new
> fields to be added don't read the URP that adds them. A small change in
> DocBuilder.java was enough to fix this for my use case, now all my fields
> returned by the sql query are later added to the schema just fine.
> I did not look in detail into multiValued fields, but maybe this small patch
> is enough for someone to look at it.
