Investigating Seeming Deadlock

Hi SOLR Community, I'm investigating a node on solr 8.3.1 running in cloud mode which appears to have deadlocked, and I'm trying to figure out if this is a known issue or not, and looking for some guidance in understanding both (a) whether this is a resolved issue in future releases or needs a

Caffeine Cache Metrics Broken?

Hi SOLR Community, I'm investigating a weird behavior I've observed in the admin page for caffeine cache metrics. It looks to me like on the older caches, warm-up queries were not counted toward hit/miss ratios, which of course makes sense, but on Caffeine cache it looks like they are. I'm using

What controls field cache size and eviction rates?

Hi SOLR Community, I've been trying to understand how the field cache in SOLR manages its evictions, and it is not easily readable from the code or documentation the simple question of when and how something gets evicted from the field cache. This cache also doesn't show hit ratio, total hits,

Caffeine Cache and Filter Cache in 8.3

Hi SOLR Community, I have a question about cache implementations based on some seemingly inconsistent documentation I'm looking at. I'm currently inquiring about 8.3, but more generally about solr version 8 too for upgrade planning. In the description in the docs for cache implementations says

Hi Paras, I'm not sure I follow. How would one replace sort by id with boosting? Thanks, Stephen On Fri, May 15, 2020, 7:43 AM Paras Lehana wrote: > As a workaround, can you try field boosting? > > On Tue, 12 May 2020 at 00:45, Stephen Lewis Bianamara < > stephen.bianam...@g

What is the logical order of applying sorts in SOLR?

Hi SOLR Community, What is the order of operations which SOLR applies to sorting? I've observed many times and across SOLR versions that a restrictive filter with a sort takes an extremely long time to return, suggesting to me that the SORT is applied before the filter. An example situation is

GC1 and StringDeduplication

Hi SOLR Community, I've been looking at performance tuning solr's GC lately. I found this helpful article on the matter. https://cwiki.apache.org/confluence/display/SOLR/ShawnHeisey One thing the article does not address is the GC1's ability to use string deduplication:

Sorting on an empty filter

Hi SOLR Community, I've observed while hosting a SOLR 6.6 installation that if I issue a query where the filter query returns an empty set but there is a sort associated with it, the query takes an extended time to execute over the query with only the filter query and no sort associated to it.

Hi SOLR Community, I have an example of a basic Japanese indexing/recall scenario which I am trying to support, but cannot get to work. The scenario is: I would like for 日本人 (Japanese Person) to be matched by either 日本 (Japan) or 人 (Person). Currently, I am not seeing this work. My Japanese text

Hello SOLR Community, I'm prototyping a collection on SOLR 6.6.3 with UUID fields, and I'm hitting some trouble with atomic updates. At a high level, here's the problem: suppose you have a schema with an optional field of type solr.UUID field, and a document with a value for that field. Any
