Yonik Seeley commented on SOLR-2272:
------------------------------------
bq. I don't think that would really work if it is a one to many relationship
but thank you for your response!
I don't see why not... the disadvantages of having everything in a single index
are:
- you can't use the same field name for different things, they must be the same
type
- efficiency and sparse fields - sorting on a field takes some memory for every
document in the index, regardless of how many documents have that field
Perhaps you could give a small example of how something could work in 2 indexes
but not 1?
