Subject Re: Join in SOLR

Hi,

I cannot guess what is 'entities' in your context, but do you want some
kind of join functionality like RDBs on Solr?
Basically, Solr is not "relational". So at first, you should consider
denormalize your RDB tables to one table/view (or issue SQL JOIN query in
DIH) to import data to Solr.

If you *really* need join like RDB on Solr, you could consult with Solr's
join feature. (That makes your system more complicated.)

Tomoko
