Difference in response times between direct to shard vs random shard with route param

Hi I'm trying to create the right design for a Solr Cloud cluster which is robust and responsive. I've been playing with different versions. I'll share details about the two versions that I'm comparing. Cluster details: 1 collection, 4 shards, 2 replicas each. 8 nodes. So 1 replica on 1 node. E

Croatian language support

Hi, according to https://solr.apache.org/guide/8_8/language-analysis.html Solr currently does not support Croatian out of the box. Does anyone have suggestions on how to implement this? I would also be interested in sponsoring the development of this. Thanks! Georg

Re: Croatian language support

Hi Georg, I did not use it in a while, but your best bet is to try hunspell stemmer. There are dictionaries for Croatian. I used to work on library for morphological analysis for Slavic languages, but I never made Solr wrapper for that. That was Java based implementation of phd dissertation wher

Solr upgrade from version 4.4

Hi all, We are currently running solr 4.4 on a 3 node cluster. We have never had an incentive to upgrade. That old solr version is heavily integrated into our infrastructure, so we always considered an upgrade to be a monumental task. We recently started looking at the new solr features and we are

Re: Solr upgrade from version 4.4

Your old schema will need minor adjustments as the classes for a lot of core types have changed. Your old configs will also just mostly need mechanical translation from one xml to another, but probably nothing major if you were using the standard /select and friends. The biggest issue for most pe

Re: Solr upgrade from version 4.4

Hi John, Solr 4.4. is very old - if you are to upgrade to 8.8 (and you should really) you'll be able to take very little with you. Your old configuration can serve as inspiration but not a direct source. It will be a big task, but if you approach it the right way you'll be fine. Solr 8.8 doe

Unrecognized command line option when starting Solr 8.7 with Java 11 Open J9

Hello, We're currently migrating from Java 8 to Java 11. On Windows, when starting Solr 8.7.0 with OpenJ9 java, we encounter the following message: JVMJ9VM007W Command-line option unrecognised: -Xlog:gc*:file="C:\solr\server\logs\solr_gc.log":time,uptime:filecount=9,filesize=20M JVMJ9GC063E U

Replication keeps failing for the Repeaters in the Solr legacy setup

Hi, We are using the legacy solr setup (I am going to refer to the nodes as leaders and followers. I think that’s what the Solr community has decided to call those). Our setup roughly looks like *Repeater (Remote DC)* --- *Followers(Remote DC)* |

RE: Unrecognized command line option when starting Solr 8.7 with Java 11 Open J9

Hi Elizaveta, I have also encountered a VerifyError on OpenJ9, on an unrelated thing. It seems that OpenJ9 is not a good choice for stability. Prefer using Hotspot either way. From: Elizaveta Golova Sent: 15 March 2021 09:02 PM To: solr-u...@lucene.apache.org

Re: Unrecognized command line option when starting Solr 8.7 with Java 11 Open J9

I know nothing about Open J9, but some quick googling suggests that OpenJ9 changed their -Xlog parsing rules at some point -- the current docs don't mention anything about some of the options you are using (other then 'file') https://www.eclipse.org/openj9/docs/xlog/ https://www.eclipse.org/o

RE: Unrecognized command line option when starting Solr 8.7 with Java 11 Open J9

Hi, Yes Chris, Open J9 have an issue on their backlog for this: https://github.com/eclipse/openj9/issues/8195 This is related to the GC_LOG_OPTS in solr.cmd. Unfortunately, this can't be set in solr.in.cmd due to: "For Java 9 or higher: GC_LOG_OPTS is currently not supported. If you set it, t
