RE: heavy reads from disk when off-heap ram is constrained

Hello Kyle, This is actually the manual [1] clearly warns for. Snippet copied from the manual: "When setting the maximum heap size, be careful not to let the JVM consume all available physical memory. If the JVM process space grows too large, the operating system will start swapping it, which

RE: Repeatable search term bug in Solr 8?

Hello Phil, Solr never returns "The website encountered an unexpected error. Please try again later." as an error. To get to the root of the problem, you should at least post error logs that Solr actually throws, if it does at all. You either have an application error, or an actual Solr problem

Repeatable search term bug in Solr 8?

All, We recently upgraded to our Drupal 8 sites to SOLR 8.3.1. We are now getting reports of certain patterns of search terms resulting in an error that reads, "The website encountered an unexpected error. Please try again later." Below is a list of example terms that repeatably result in this

heavy reads from disk when off-heap ram is constrained

Hi All, Something we learned recently that might be useful to the community. We're running solr in docker, and we've constrained each of our containers to have access to 10G of the host's ram. Also, through `docker stats`, we can see the Block IO (filesystem reads/writes) that the solr process is

Paras, Thank you for this response! Yes, you are being clear __ Regarding the assumptions you make for MRR, do you have any research papers to confirm that these user behaviors have been observed? I only ask because this paper http://yichang-cs.com/yahoo/sigir14_SearchAssist.pdf talks about how

Javadocs are not linkable

Hi, I recently noticed that the SOLR javadocs hosted by lucene are not linkable as the „package-list“ file is not downloadable. Is this on purpose? $ curl https://lucene.apache.org/solr/8_4_0/solr-solrj/package-list 301 Moved Permanently Moved Permanently The document has moved https://lucene

Re: Upgrading from 6.5.0 to 8.4.1

Despite deleting all the docs, what I suspect is that you still have segments that have no live docs in them, but still preserve the 6x marker. That said, what’s the point of the 7.7.2 step? Why not just index once into a pristine 8.4.1 cluster? You could even do this on a few machines, serving

Re: Upgrading from 6.5.0 to 8.4.1

You did a reload and not a reindex? Probably the best is to delete the collection fully, create it new and index then . > Am 27.02.2020 um 14:02 schrieb Pavel Polivka : > > Hello, > > I am doing upgrade of SolrCloud cluster from 6.5.0 to 8.4.1. > > My process is: > > Upgrade to 7.7.2. > Rec

Upgrading from 6.5.0 to 8.4.1

Hello, I am doing upgrade of SolrCloud cluster from 6.5.0 to 8.4.1. My process is: Upgrade to 7.7.2. Reconfigure my solrconfig to have 7.7.2, reload collections. Delete all docs in all collections and index them again. Upgrade to 8.4.1. This step always fails for me with message in logs sayin

Re: Rule of thumb for determining maxTime of AutoCommit

Hey Kaya, How are you adding documents to your index? Do you control this yourself or do you have multiple clients (curl, solrJ, calls directly to /update*) updating data in your index as I suspect (based on your hard and soft commit settings) that a client may be causing your soft commits mak

Position And Offset in Solr Query

Re: Rule of thumb for determining maxTime of AutoCommit

Hi Kaya, Since you do not have soft commits, you must have explicit commits somewhere since your hard commits are configured not to open searcher. Re warming up: yes - you are right. You need to check your queries and warmup numbers in cache configs. What you need to check is how log does warmup

I this the issue is NFS. If you mode all to a NVMe or SSD local to the server indexing process will work fine. NFS is the wrong filesystem for solr. I hope this helps. Il giorno gio 27 feb 2020 alle ore 00:03 Massimiliano Randazzo < massimiliano.randa...@gmail.com> ha scritto: > Il giorno mer 26
