Solr multi-core essentially just lets you run multiple seperate distinct
Solr indexes in the same running Solr instance.
It does NOT let you run queries accross multiple cores at once. The
cores are just like completely seperate Solr indexes, they are just
conveniently running in the same Solr instance. (Which can be easier and
more compact to set up than actually setting up seperate Solr instances.
And they can share some config more easily. And it _may_ have
implications on JVM usage, not sure).
There is no good way in Solr to run a query accross multiple Solr
indexes, whether they are multi-core or single cores in seperate Solr
doesn't matter.
Your first approach should be to try and put all the data in one Solr
index. (one Solr 'core').

Hi,
I have a need to index multiple applications using Solr, I also have the
need to share indexes or run a search query across these application
indexes. Is solr multi-core - the way to go? My server config is
2virtual CPUs @ 1.8 GHz and has about 32GB of memory. What is the
recommendation?
Thanks,
