The advantages of a multi-core setup are configuration flexibility and dynamically changing available options (without a full restart).

For high-performance production solr servers, I don't think there is much reason for it. You may want to split the two indexes on to two machines. You may want to run each index in a separate JVM (so if one crashes, the other does not)

Maintaining 2 indexes is pretty easy, if that was a larger number or you need to create indexes for each user in a system then it would be worth investigating the multi-core setup (it is still in development)

Hello,

Until now, i've used two instance of solr, one for each of my collections ; it 
works fine, but i wonder
if there is an advantage to use multiple indexes in one instance over several 
instances with one index each ?
Note that the two indexes have different schema.xml.

Thanks.

Hi,

I am looking for the way to utilize the multiple indexes for signle sole
instance.
I saw that there is the patch 215  available  and would like to ask someone
who knows how to use multiple indexes.

Thanks,
