Re: [External] : Re: Querying Solr Locally through Java API without using HttpClient

Hi Chris, Thanks for the details.. Our use case is simple, we have standalone solr servers, and custom request handler (plugin) is already defined and working as expected. The ask is we have to enhance the functionality of the Custom Request handler by providing a update feature as part of the

RE: Solr 9.1 performance

Workaround tested and no difference with or without it. New cloud set up with 1200mb heap for each instance and 32gb system RAM on each server. I'm seeing just over 20gb in system cache. Anti-virus exclusions applied and system doesn't appear to be swapping unnecessarily. One thing I have n

FieldCache and _version_field

Hi, One of my customers has a huge collection (1.5 billion docs across 14 shards). All fields are correctly configured in order to enable docValues except _version_. They are still using the old configuration with indexed=true instead of docValues and hence _version_ populate FiledCache in JVM hea

Re: FieldCache and _version_field

Re: FieldCache and _version_field

Hi Mikhail, Thank you for the response. More details. Solr is version 7.7.0 and collection replicas are TLOG. I will check, but I don't think atomic updates are required. Regards Dominique Le mar. 6 déc. 2022 à 15:43, Mikhail Khludnev a écrit : > Hello, Dominique. > I suppose it's used for u

Re: Wired behavior of maxClauseCount restriction since upgrading to solr 9.1

: I'm happy to provide some details as I still do not really understand the : difference to the situation before. The main difference is coming from the changes introduced in LUCENE-8811 (Lucene 9.0) which sought to ensure that the "global" maxClauseCount would be honored no matter what kind o

Re: Wired behavior of maxClauseCount restriction since upgrading to solr 9.1

Hi Hoss, This is a really helpful explanation! Even though I already shifted to the usage of the {!terms} query for such large boolean clause queries, it feels a lot better to know how and why things behave differently compared to the 8x solr version. Thanks! Michael On Tue, Dec 6, 2022 at 7:32
