Nested documents limitations and cautions

Hi, We are studying a solution that takes advantage of nested documents and therefore we are looking for information on the pros and cons and limitations that this solution offers. Furthermore, we wish to understand in which case is better to use nested documents or query time joins. Further Have t

Re: Nested documents limitations and cautions

Hi Isabella, back in the day I wrote a blog post about nested documents, not strictly related to pros and cons but can be useful: https://sease.io/2019/06/apache-solr-childfilter-transformer.html In terms of pros and cons, exploring the details of nested documents will surely require a bit of time

Re: hnsw parameters for vector search

What does your synthetic randomized benchmark look like? Did you try different values for hnswMaxConnections and hnswMaxConn. Do your curves wildly differ from https://ann-benchmarks.com/luceneknn.html ? On Tue, Jan 30, 2024 at 3:49 PM Moll, Dr. Andreas wrote: > Hi, > > the hnsw documentation f

Re: Nested documents limitations and cautions

Hi Alessandro, Thank you for your detailed answer. As I understand it, nested documents speed up searches on hierarchical documents compared to Query Time Joins andc onsume fewer resources but could create problems during reindexing. Are there any studies to understand if there are limits to the n

Block MAX WAND feature use

Hi All, To leverage the query time improvements that come with the Block MAX WAND feature, what are the required configurations? I am on solr 9.1.1 version. As per docs, including "minExactCount=100" query param should do it, however I don't see any drop in query time, it is more or less the sa

Dataimport - Optimize (Solr Version 8.11.2)

Why does *Optimize* in the *dataimport* section of solr Admin UI duplicate the records. A new copy is created of each record. "*id*" and "_*version*_" are different, everything else is the exact copy. Each time I run Optimize, the initial number of records get added again. Initial number - *Num Doc

Re: Block MAX WAND feature use

Is it possible to benchmark the query performance across a larger set of queries? You can leverage Solr Bench, if needed. https://github.com/fullstorydev/solr-bench On Thu, 1 Feb, 2024, 11:20 am Ishan Chattopadhyaya, < ichattopadhy...@gmail.com> wrote: > Some documentation is here > https://solr.

Solr9 support for Tomcat10

Hi All, We are migrating Tomcat 9 to 10.1 in our product. As part of this migration namespace Javax is changed to Jakarta. We are using Solr9 as an embedded web app. We have a custom SolrDispatchFilter which extends the org.apache.solr.servlet.SolrDispatchFilter which is still using javax. Becau

Re: Solr9 support for Tomcat10

Hi Tricky noe. You may want to weigh in on https://issues.apache.org/jira/browse/SOLR-16441 and perhaps help it move forward. Once Solr is on Jetty 11 or 12 this should be possible. But don’t hold your breath until we start planning a Solr 10 release, probably after Lucene releases v10. But y
