Hi Fred, Yeah, I realised that on my testing node with n_val of 3 I was getting the triple of results in the count... that is not ideal.
I was just concerned on how much extra-work would get Riak to talk with SOLR and compile data against hitting SOLR directly... For my tests these days, seems the /search interface is pretty fast and it may not be a real problem for Riak... but still have my fears from Riak 0.14 an Riak 1.4 Thanks, Alex On Mon, May 16, 2016 at 4:49 PM, Fred Dushin <fdus...@basho.com> wrote: > Hi Alex, > > Other people have chimed in, but let me repeat that while the > internal_solr interface is accessible via HTTP (and needs to be, at least > from Riak processes), you cannot use that interface to query Solr and > expect a correct result set (unless you are using a single node cluster > with an n_val of 1). > > When you run your queries through Riak, Yokozuna, the component that > interfaces with Solr, will use a riak_core coverage plan to generate a > distributed Solr filter query across the entire cluster that guarantees > that for any document stored on all Solr nodes in the cluster, the query > will select one (and only one) replica.
