I wrote a Python program that:

What are some of the suggested loadbalancers for solrcloud? Can AWS ELB be
used for load balancing?

Adding to Shawn's comments.
You've pretty much nailed all the possibilities, it depends on
what you're most comfortable with I suppose.
The only thing I'd add is that you probably have dev and prod
environments and work out the correct schemas on dev then
migrate to prod (at least that's what

In your setup, the load balancer prevents single points of failure.
Since you're pinging a URL, what happens if that node dies or is turned off?
Your PHP program has no way of knowing what to do, but the load
balancer does.
Your understanding of Zookeeper's role shows a common misconception.
Thanks for your reply. I have a follow up question. Why is a load balancer
needed? Isn't that the job of zookeeper to loadbalance queries across solr
nodes?
I was under the impression that you send query to zookeeper and it handles
the rest and sends the response back. Can you please enlighten
You send your queries and updates directly to Solr's collection e.g.
http://host:port/solr/. You can use any Solr node for
this request. If the node does not have the collection being queried then
the request will be forwarded internally to a Solr instance which has that
collection.
ZooKeeper is
I have a question regarding querying in solrcloud.
I am working on php code to query solrcloud for search results. Do I send
the query to zookeeper or send it to a particular solr node? How does the
querying process work in general.
Thank you

Hi,
We're transitioning from Solr 4.10 to 7.x and working through our options
around managing our schemas. Currently we manage our schema files in a git
repository, make changes to the xml files, and then push them out to our
zookeeper cluster via the zkcli and the upconfig command like:
The documentation does not say that Solr uses the zk client 3.4.11. It says,
"Solr currently uses Apache ZooKeeper v3.4.11.” That is on the page titled
"Setting Up an External ZooKeeper Ensemble” in the section "Download Apache
ZooKeeper”. Maybe that is supposed to mean “The Solr code uses the

Hi Solr-Team,
I am benchmarking solr with the German Wikipedia pages on 4 nodes (Running
on ports , 9998, 9997 and 9996), 4 shards, replication factor 2):

Thanks. I think that's a good point that it helps recognize port conflict at
start up. Although that scenario is unlikely in my case, I am going to try
to get it installed.

Hi Tushar,
You're right; the docs are a little out of date there.
Krb5HttpClientConfigurer underwent some refactoring recently and came
out with a different name: Krb5HttpClientBuilder.
The ref-guide should update the snippet you were referencing to
something more like:

Hi Jesse,
you are correct, the variable 'bestScore' used in the

it is used to normalise the terms score :

e.g.
Queue -> Term1:100 , Term2:50, Term3:20, Term4:10
The minScore will be 10

Hi,
It is probably the best if you merge some of your collections (or all) and have
discriminator field that will be used to filter out tenant’s documents only. In
case you go with multiple collections serving multiple tenants, you would have
to have logic on top of it to resolve tenant to
