SolrJ compatibility

Hello, I am looking for information which version of the SolrJ client is compatible with the Solr server. So far I only found some information in the cwiki where it says: "SolrJ generally maintains backwards compatibility, so you can use a newer SolrJ with an older Solr, or an older SolrJ with

Solr scale function

Hi all, playing with the solr scale function I found a few corner cases where I need to scale only the results set. I found a workaround that works but it does not seem to be viable, because if I add an fq parameter the scale function still continues to work only on the q param . For example wit

Re: Solr scale function

Hello Vincenzo, I'm not getting your point: > if I add an fq parameter the scale function still continues to work only on the q param . well, but the function actually refers to q param: scale(sum(price,query($q)), 0, 1). What's your expectation values of query($q) with "q":"popularity:(1 OR

DocValues usage

Hi, We are planning to introduce docValues and reduce the usage of fieldcache in our application. I have a few doubts on these. Please help me to clarify them. 1) Will there be a performance impact if we use docValues as it does I/O read? Especially at the time of index generation? 2) Are there

Re: Solr scale function

Hi Mikhail, I'm trying to apply the scale function only to the result set (and not to the entire collection). And I discovered that adding "query($q)" to the scale function does the trick. In other words, adding "query($q)" forces solr to restrict the scale function only to the result set. But if

For those using SolrCloud, you can read this in the upgrade notes: https://solr.apache.org/guide/solr/latest/upgrade-notes/major-changes-in-solr-9.html "If using CloudSolrClient to connect to your SolrCloud

Re: SolrJ compatibility

We had one 4.x cluster that was difficult to migrate, so until recently we were using SolrJ 4.x with our new Solr 8.7 clusters and with a Solr 4.10.4 cluster. We were not doing anything fancy like faceting. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog)

Upgrade SOLR 7.3 to 8.9，json.facet query performance drops a lot

Hello everyone. We recently upgraded our online environment to a new solr version(8.9.0) from 7.3, we found that facet query performance decreased a lot. Solr 7.3 take about 100 milliseconds, but Solr 8.9 may take about 500 milliseconds. We exclude the effects of GC and caching. Are there

I don't think this will make a huge difference, but would you be able to retest with Solr 8.11.1 instead of 8.9? Mike On Tue, May 31, 2022 at 10:54 AM slly wrote: > Hello everyone. > > > We recently upgraded our online environment to a new solr version(8.9.0) > from 7.3, we found that facet que

`json.facet` covers a lot of ground and can do a lot of different things under the hood. Would you be able to share more specific information about the kinds of `json.facet` request you're making, configuration of the fields in question, etc.? On Tue, May 31, 2022 at 11:54 AM slly wrote: > > Hell

Collapsing on a field works, but expand=true does nothing

I’m working on the collapse/expand functionality. I query for books, and I want to collapse my search results on their tf1flrid, basically a family ID. I also want to do an expand so I can see what titles were collapsed out. I’m looking at the docs here: https://solr.apache.org/guide/8_11/col

Solr Cloud and /export

What do I have to configure or add to the request to have an /export call respond with docs from all shards? I currently only get documents from the leader when making an /export call (solr 8.11.1). Cheers, JAG

Re: Re: SolrJ compatibility

If the solr indexing packages among all the different languages suddenly need to upgrade just because of solr cloud and can’t use http requests for indexing, that would be a bad bad thing. The cloud internals should handle anything indexing wise beyond “here is a document and it’s metadata” much li

Thanks Mikhail! Regarding the id field, is it possible that while doing faceting or sorting, the id fields will be loaded in field cache by default? On 2022/05/31 21:27:57 Mikhail Khludnev wrote: > Hi, Poorna. > Pls check inline below. > > On Tue, May 31, 2022 at 4:21 PM Poorna Murali > wrote: >
