: I have a group of subindex, each of which is a core in my solr now. I want : to make one query for some of them, how can I do that? And classify response : doc by index, using facet search?
some background: "multi core" is when you have multiple solr "cores" on one solr instance; each "core" can have different configs. "distributed search" is when you execute a search on a "core" and specify in the query a list of other cores on other solr instances to treat as "shards" and aggregate the results from all of them; each "shard" must have identicle schemas. That said: you can to a distributed search, across a bunch of "shards" that are all on the same solr instance. if you index a constant value in each one identifying which sub-indx it comes from, you should have what you're looking for. -Hoss
