Thanks Erick,
We've never merged indexes. We don't use the MapReduceIndexerTool, but do
use an external map reduce process to reindex. To reindex from an empty
state we have a map reduce job which runs on a separate HBase cluster and
indexes into this shard. During this job each mapper is concurre
This is indeed strange. First of all, forget about explanations that involve
the transaction log etc. When Lucene opens a searcher, it is only for closed
segments, the tlog has nothing to do with that.
Have you ever merget indexes? The MapReduceIndexerTool, if you ever used it,
does not de-dupl

Hi, all. We’re upgrading an old Solr 3.5 setup (master/slave replication) to
SolrCloud (v7 or v8) and with the addition of a new data center (for dual data

In my solr schema I have set a uniqueKey of "id" where the id field is a

documents with the same "id" field, but different internal `docid`s. This

Hi,
I tried to upgrade from 8.0 to 8.1. I noticed that there is an issue with
collection aliases, but I am not 100% sure it is due to the upgrade.
Situation:
I have a collection called c_testcollection.
I have an alias called testcollection.
Alias "testcollection" points to "c_testcollection".

I think it’s the wrong question to ask. By using docaValues you’ll be able to
significantly reduce the heap allocated to the Java process, reduce the
overhead of garbage collections, reduce the possibility of nodes going into
recovery and increase stability generally. Compared to those gains, pe
Hi, I’ll advised you to extend the class SolrCloudTestCase, which extends the
MiniSolrCloudCluster. Theres a hello world example in the solr source at
https://github.com/apache/lucene-solr/blob/master/solr/core/src/test/org/apache/solr/HelloWorldSolrCloudTestCase.java.
Here’s how I setup a clust
Thanks Erick,
I understand using docvalue should improve query performance. Please correct me
if my understanding is incorrect.

Yes that worked.

Use docValues on all fields you group, facet or sort on.
NOTE: you _must_ re-index from scratch, I’d index to a new collection and start
over. Paradoxically your index size _on disk_ will increase, but your JVM will
need drastically less heap. See:

Hi,
I don't seem to be able to get the merge core feature to work with Solr 7.2.1.
I'm using the srcCore parameter method documented at

Derrick,
This makes me think you do not have a default query field identified. Look in
your solrcong.xml file for the requesthandler you are calling and see if it has
the "df" parameter set. Should look something like:

Hello, Pratick.
Welcome to mysterious world of Solr testing. The best way is to find
existing test closest to your problem field, copy in and amend necessarily.
