Description

TODO

Let's remove BlockJoinFacetComponent because it doesn't work with BooleanScorer aka term-at-time. It's advised to use BlockJoinDocSetFacetComponent instead.

Original Description

query like this:

http://localhost:8983/solr/core0/bjqfacet?q=*:*%20{!parent+which%3Dtype_s:parent}type_s:child&facet=true&child.facet.field=SIZE_s

throws:

java.lang.UnsupportedOperationException
        at org.apache.lucene.search.FakeScorer.getChildren(FakeScorer.java:60)
        at org.apache.solr.search.join.BlockJoinFacetCollector.getToParentScorer(BlockJoinFacetCollector.java:66)

Not that this query makes much sence, but don't expect naked exception.

This only happens when using BlockJoinFacetComponent - BlockJoinDocSetFacetComponent seems to do OK.
