Hi Mark, Thanks for confirming Dwane's advice from your own experience. I will shift to a streaming expressions implementation. Best Goutham On Fri, Sep 25, 2020 at 7:03 PM Mark H. Wood wrote: > On Fri, Sep 25, 2020 at 11:49:22AM +0530, Goutham Tholpadi wrote: > > I have around 30M documents in

Thanks a ton, Dwane. I went through the article and the documentation link. This corresponds exactly to my use case. Best Goutham On Fri, Sep 25, 2020 at 2:59 PM Dwane Hall wrote: > Goutham I suggest you read Hossman's excellent article on deep paging and > why returning rows=(some large number

Re: Solr 8.6.2 UI issue

Sounds strange. If you had Solr installed previously, it could be cached Javascript. Force-reload or try doing it in an anonymous window. Also try starting with an example (solr/start -e techproducts). Finally, if you are up to it, see if there are any serious errors in the Browser's developer co

SOLR Cursor Pagination Issue

Good afternoon, Could you please suggest us a solution: during data updating process in solrCloud, requests with cursor mark return incorrect data. I suppose that the results do not follow each other during the indexation process, because the data doesn't have enough time to be replicated betwe

Hi Goutham, I agree with Rahul, avoid large deletebyquery. It you can, prefere one query to get all the ids first than use ids with deletebyid Regards Dominique Le ven. 25 sept. 2020 à 06:50, Goutham Tholpadi a écrit : > I spoke too soon. I am getting the "Connection lost" error again. > > I

Hi, This would be a Java VM option, not something Solr itself can know about. Take a look at this article in comments. May be it will help. https://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html?showComment=1347033706559#c229885263664926125 Regards Dominique Le jeu. 24 sept.

Re: Solr 8.6.2 text_general

Uhhh, this is really dangerous. If you’ve indexed documents since upgrading, some were indexed with multiValued=false. Now you’ve changed the definition at a fundamental Lucene level and Things Can Go Wrong. You’re OK if (and only if) you have indexed _no_ documents since you upgraded. But

It worked. I just added multiValued="true". Thanks for all your help. Regards, Anuj On Fri, 25 Sep 2020 at 18:08, Alexandre Rafalovitch wrote: > Ok, something is definitely not right. In those cases, I suggest > checking backwards from hard reality. Just in case the file you

Ok, something is definitely not right. In those cases, I suggest checking backwards from hard reality. Just in case the file you are looking at is NOT the one that is actually used when collection is actually setup. Happened to me more times than I can count. Point your Admin UI to the collection

Goutham I suggest you read Hossman's excellent article on deep paging and why returning rows=(some large number) is a bad idea. It provides an thorough overview of the concept and will explain it better than I ever could (https://lucidworks.com/post/coming-soon-to-solr-efficient-cursor-based-ite
