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. If you were to run your query locally using the internal_solr interface, your query would not span the cluster (likely missing documents on other nodes) and may have duplicates (e.g., in degenerate cases where you have more than one replica on the same node). I hope that helps explain why using the internal_solr interface is not only not recommended, it's also not going to give you the results you expect. -Fred > On May 15, 2016, at 4:18 AM, Alex De la rosa <alex.rosa....@gmail.com> wrote: > > Hi Vitaly, > > I know that you can access search via HTTP through Riak like this: > > http://localhost:8098/search/query/famous?wt=json&q=leader:true > <http://localhost:8098/search/query/famous?wt=json&q=leader:true> AND > age_i:[25 TO *] > > I didn't find documentation about this, but according to your words I could > access SOLR directly like this? > > http://localhost:8093/internal_solr/famous/select?wt=json&q=leader:true > <http://localhost:8093/internal_solr/famous/select?wt=json&q=leader:true> AND > age_i:[25 TO *] > > If I go through "8098/search" would it be adding extra stress into the Riak > cluster?
