    Description

      According to Solr documentation  QParser is treated as a legal plugin.

       

      However, it is impossible to create an effective ToParentBlockJoin query without copy-pasting(BitDocIdSetFilterWrapper class and getCachedFilter method from BlockJoinParentQParser) or dirty hacks(like creating org.apache.solr.search.join package with some accessor method to package-private methods in plugin code and adding it in WEB-INF/lib directory in order to be loaded by the same ClassLoader).

      I don't see a truly clean way how to fix it, but at least we can help custom plugin developers to create it a little bit easier by making BlockJoinParentQParser#getCachedFilter public and BlockJoinParentQParser#BitDocIdSetFilterWrapper and providing getter for BitDocIdSetFilterWrapper#filter.
