Solr Block-Join requires uniqueKey field to be int?
Hello all,
We have been using strings for our uniqueKey field and discovered that Solr
Block-Join requires the uniqueKey field to be an int. This is because the
magic field _root_ is required to be an int, and for children it gets
populated from the uniqueKey field of the parent record.
Would it be possible to change this to accomodate uniqueKeys that are
strings or is there some operation that requires ints for the field that
links the parent and child records in the Solr Block-Join logic?

Thanks Yonik,
It works fine with a String.
How embarassing, Somehow I managed to accidentally set _root_ to an int in
my schema. Don't know how I did it.

Are you sure it doesn't work with String? The example field has
_root_ defined to be:
<field name="_root_" type="string" indexed="true" stored="false"/>
