Join is not only query time related. Join is the Solr approach to nested documents. Block join and Query time join are 2 different strategies with different pros and cons . Basically :
Block Join : - force you to follow a specific indexing strategy - if you want to update a child you need to update the whole block ( parent +children) + 4-5 times faster then query time join Query Time Join + you can index the data how you want, even in different cores + you can update single children - it is "slow" What do you mean with "strange" indexes ?
